Landslide is one of natural disasters, and after the landslide occurs, serious life and property safety loss is often caused to the local area. In the current landslide research, a plurality of scholars pay attention to the cause mechanism of landslide, and then focus on the motion characteristics, disaster-causing effect and the like of landslide. Loess landslides are different in types, and the disaster-causing effects generated after occurrence are completely different. The loess landslide can be divided into four types, namely a loess in-layer landslide, a loess-mudstone bedding landslide, a loess-mudstone cut-layer landslide and a loess-mudstone contact surface landslide according to the rock-soil type, the loess in-layer landslide and the loess-mudstone cut-layer landslide are usually high in speed when occurring, the generated disaster-causing effect is obvious, and the energy release mode of the loess-soil landslide belongs to an instant release type; loess mudstone bedding landslide often slides along the bedding surface of the mudstone, the sliding speed is higher when the gradient is higher, and the three types of landslides can be finished after dozens of minutes to several hours from the starting to the end of sliding. However, the loess-mudstone contact surface landslide has different energy release modes from the loess-mudstone contact surface landslide, the landslide is usually low in speed during starting, the typical slow-moving low-speed characteristic is presented macroscopically, the energy release mode is extremely slow, through investigation, the landslide slides from hours to months, the landslide is not easy to be found due to the low speed in the initial stage, damage is caused during landslide, such as house cracking, house collapse, road retaining wall damage, pavement cracking, river channel blockage, farmland damage and the like, serious economic loss is caused to the local area, the Gansu Tianshuangwang landslide generated in 2013 and Gansu Tongmang Xiaozhuang landslide generated in 2019 cause serious overall loss of three villages, local villages are forced to be moved integrally, the local social economic development is seriously influenced, and a plurality of roads are forced to be re-routed for repairing.
The fundamental reason for serious harm caused by the creeping landslide is that the creeping landslide is difficult to identify in the early stage, cracks in the landslide are often formed after the landslide occurs for a period of time, the landslide stops after sliding once in the investigation, and the sliding is generated again when the rainy season or the spring comes, so that vegetation in the water and day area with wide development of the landslide grows well and is difficult to find, and huge barriers are brought to the landslide investigation.
In conclusion, a reliable creeping landslide identification method is urgently needed, the method needs to be simple, convenient and easy for landslide investigators to master in time, and can be easily identified from a satellite map, and the phenomenon seen on a guard sheet plays an important role in promoting landslide later-stage identification because the large-scale landslide investigation needs to be interpreted by the guard sheet. In the existing research, landslide cracks, landslide depressions, steep ridges at the rear edge of the landslide, a rear edge round-seat-shaped structure, heaped deposits at the front edge and other methods are commonly utilized to carry out early identification on the landslide, the method has a limited application range on the landslide of a creeping sliding loess-mudstone contact surface, the phenomena are all not obvious at the early stage of the landslide, cracks can develop, but the process is slow, the cracks in the farmland are often directly filled by local common people, huge challenges and difficulties are brought to landslide investigation, including revival of old landslides, and the old landslides are not easy to find.
If the landslide is identified on site by using methods such as landslide cracks, landslide depressions, accumulations with raised front edges and the like, the phenomena such as landslide depressions and raised front edges do not occur in the early stage of the landslide of the contact surface of the creeping loess mudstone, the cracks occurring in the early stage of the landslide are very small, local vegetation grows vigorously, and the method has limited applicability in the landslide identification.
If the start and the formation of the landslide are recognized early by the contour such as the steep ridge at the rear edge of the landslide, the coil-shaped structure at the rear edge, and the like, since the newly generated creeping type landslide is not formed at the rear edge steep ridge and the coil-shaped structure, the method has limited applicability and cannot recognize the landslide.
If landslide is recognized by means of rock-soil body settlement, an inSAR technology, landslide surface segmentation, a symmetrical depth network combined multi-scale pooling method and the like, obvious rock-soil body settlement and sliding surface deformation are not generated when the creeping type landslide is formed, and the cost for purchasing multiple-stage images is high in the inSAR technology.
If the method of fusing the DEM, the optical remote sensing, the deformation information and the like is used for early identification of the landslide, the SAR image is also used in the implementation of the method, multiple periods of image data in the current area need to be purchased in the early period, the generated cost is high, the technology is difficult to master by common technicians, and the applicability of the technology is limited.
Based on the above, the method is easy to master, can be used in both a satellite slide and field landslide identification, and provides a new thought and method for disaster prevention and reduction work.
Aiming at the problems that the existing landslide risk identification mode cannot meet the requirements of landslide identification accuracy, dependence on artificial experience is reduced, operation is simple and the like, the embodiment of the application provides a landslide risk identification method, wherein the occurrence and movement conditions of landslide can be indirectly obtained through the growth conditions of tree crowns by acquiring the respective isotope contents of main crowns and side branches of target trees which are planted in a target soil area and have isotope nutrient solutions dripped in root soil; judging whether the main root of the target tree is damaged or not according to the respective isotope contents of the main crown and the side branch, effectively improving the operation convenience and efficiency of the landslide risk identification mode, reducing the technical difficulty and the operation complexity, and does not need to rely on manual experience, can effectively improve the accuracy of identifying the risk of the landslide on the basis of effectively reducing the labor cost and the time cost, particularly can effectively improve the accuracy, the operation convenience and the like of identifying the risk of the landslide aiming at the creeping type landslide which is difficult to be found manually compared with the landslide in other forms, and then can effectively improve landslide risk identification's degree of automation and intelligent degree, and guarantee personnel, vehicle and the house safety of the regional that takes place the peristaltic landslide, improve landslide risk identification technical staff and live in the user experience who probably sends the regional personnel of peristaltic landslide.
Based on the above content, the present application further provides a landslide risk identification device for implementing the landslide risk identification method provided in one or more embodiments of the present application, where the landslide risk identification device may be an electronic device such as a server, and the landslide risk identification device may be in communication connection with each detection device, a sensor, and a client device by itself or through a third-party server, and the landslide risk identification device may receive a landslide risk identification instruction sent by the client device, and collect, according to the landslide risk identification instruction, respective isotope contents of a main crown and a side branch of a target tree that is planted in a target soil area and whose root soil is drip-irrigated with an isotope nutrient solution; and judging whether the main root of the target tree is damaged or not according to the respective isotope contents of the main crown and the side branches, if so, identifying the target soil area as a landslide risk area, and sending landslide risk area identification result data to client equipment of a user by the landslide risk identification device.
In another practical application scenario, the part of the landslide risk identification performed by the landslide risk identification apparatus may be performed in the server as described above, or all operations may be performed in the user end device. Specifically, the selection may be performed according to the processing capability of the user end device, the limitation of the user usage scenario, and the like. This is not a limitation of the present application. If all the operations are completed in the customer premises equipment, the customer premises equipment may further include a processor for performing a specific process of landslide risk identification.
In one or more embodiments of the present application, the woody plant performs water and nutrient absorption through the root system, and transports water and nutrients to various parts of the plant growth after absorbing water and nutrients. The water absorption of the plant root is mainly carried out at the root tip part, and the water absorption is less in root crowns, meristematic regions and elongation regions due to the fact that the conduction tissues are not mature, the intercellular water migration resistance is large and the like. The root hair area has a large amount of root hair development, forms a very large absorption area, and has the advantages that the conduction tissue of the root hair area is basically mature, the water transmission resistance is small, and the root hair area has the maximum water absorption capacity. After the landslide occurs, broken rock-soil bodies continuously slide and move to cause that root hair areas of woody plants are broken and damaged, even main roots in partial areas are broken and damaged, so that root crowns are separated from the main roots, the water absorption capacity of the plants is greatly reduced, and the obvious withering phenomenon appears in most areas of the tree crowns.
The roots may absorb minerals from the soil solution or absorbed by the soil particles. The site of mineral uptake by the root is also mainly the tip of the root, as is moisture uptake, with the root hair region being the most ion-active. The existence of root hairs can greatly increase the contact area of the roots and the soil environment. After the landslide occurs, broken rock-soil bodies continuously slide and move, so that root hair areas of woody plants are broken and damaged, even main roots in partial areas are broken and damaged, root crowns are separated from the main roots, and the mineral absorption capacity of the plants is greatly reduced.
As described above, water and minerals required for the growth of aerial parts are mainly supplied from the root system, and the roots are the center of cytokinin synthesis in the whole plant and transported to the aerial tree crowns or the like after formation. Not only substance communication but also signal transmission relationship exists between roots and crowns, and the growth condition of the upper tree crowns can be regulated and controlled when nutrient components in soil are changed. The sliding depth of different positions on the landslide is different, the root system of woody plants is broken in the sliding process of the slope body, the root tip part of the main root system is broken and separated, the crown of the trunk is dried, the rock and soil body at the position can be directly judged to move through the phenomenon, the displacement is generated, the displacement amount generates an accumulation effect, the root system of the plants is damaged, the crown of the crown is dried macroscopically, and the growth of the lateral branches completely depends on the lateral roots and other root systems to maintain.
In the field investigation, the phenomenon that crown withering occurs at the top of most middle-aged trees in the main sliding direction of the landslide, lateral branches grow normally, surrounding equal trees grow normally, inclined telegraph poles and the like in the main sliding direction are used as evidences, and the distribution position of damaged trees can be judged to be the main sliding direction of the landslide by combining the house cracking and the like in the main sliding direction.
The creeping type landslide identification method based on mutual feeding of the root crowns is provided by the application, because vegetation in the Tianshui region in Gansu is flourishing in growth, the underground water level is high, cracks and the like generated after landslides occur are not obvious, and macroscopic sites such as obvious steep campsides and the like do not appear, and whether old landslides survive or not and whether landslides are formed on the sites are difficult to judge. The method is simple and easy to understand, field technicians can quickly master the method, important technical support is provided with field landslide identification, necessary measures can be taken after early identification to reduce the damage of landslide, and contribution is made to disaster prevention and reduction.
The following embodiments and application examples are specifically and individually described in detail.
In order to solve the problems that the existing landslide risk identification mode cannot meet the requirements of landslide identification accuracy, reduction of dependence on manual experience, simplicity in operation and the like, the application provides an embodiment of a landslide risk identification method, and referring to fig. 1, the landslide risk identification method executed based on a landslide risk identification device specifically includes the following contents:
step 100: and collecting the respective isotope contents of the main crown and the lateral branches of the target tree which is planted in the target soil area and the root soil of which is drip-irrigated with the isotope nutrient solution.
In step 100, the landslide risk-based identification device may send an isotope collection instruction to an isotope collection and detection device, so that the isotope collection and detection device fixedly disposed on the target tree collects respective isotope contents of a main crown and a side branch of the target tree according to the isotope collection instruction, and sends the collected respective isotope contents of the main crown and the side branch of the target tree to the landslide risk-based identification device.
In the specific description of the isotope collecting and detecting device, the isotope collecting and detecting device needs to at least include an isotope collecting function and an isotope detecting function, and first respectively collects respective samples of a main crown and a lateral branch of a target tree through the isotope collecting function, then detects the isotope content of the main crown from the collected main crown sample of the target tree through the isotope detecting function, and detects the isotope content of the lateral branch from the collected lateral branch sample of the target tree.
In a specific example of the isotope collecting and detecting device, the isotope collecting and detecting device may be an isotope detector of (KMZ-50) type, and the isotope detector and the target tree are specifically arranged in the following manner: isotope monitoring detection is distributed at the periphery of a plant root system and a drip irrigation position, is distributed at the branch and leaf parts of the tree, and is used for calculating and analyzing the total plant absorption amount according to the total titration amount and the peripheral distribution condition and the content in the branch and leaf.
It is understood that the isotope may be an isotope of hydrogen in water.
Step 200: and judging whether the main root of the target tree is damaged or not according to the respective isotope contents of the main crown and the side branch, and if so, identifying the target soil area as a landslide risk area.
If the main root of the target tree is judged and known not to be damaged in the step 200, after waiting for a preset detection time period, returning to the step 100, and collecting and judging whether the target soil area is a landslide risk area or not again.
It can be understood that, if the main root of the target tree is damaged, it may be preliminarily determined that the target soil area where the current target tree is located has landslide, and thus the target soil area may be marked as a landslide risk area. Then, a notification message that the target soil area is the landslide risk area may be sent to the client device of the operation and maintenance staff for display, a landslide risk warning message may be sent for the landslide risk area for the target soil area, and in order to further improve accuracy of landslide risk identification and effectively reduce a false alarm rate, the landslide risk area may be further assisted with landslide identification on the basis of step 200, which is described in detail in the following embodiments.
