Description

Riverbank, river, a kind of desert sand damage governing system

Technical field

The utility model relates to sand damage prevention and control field, relates in particular to riverbank, river, a kind of desert sand damage governing system.

Background technology

China desert, Gobi desert, blowland and desertification land 1,670,000 Km ²17.4% of ，Zhan China land area.Control of desert is paid close attention to the fields such as means of transportation (railway, highway), transmission line of electricity, petroleum pipeline, productive life facility (farmland, residence, factory) for a long time.Desert area is also distributed with a large amount of rivers, such as, the Nile in Sahara Desert, Ning Meng section, the upper reaches of the Yellow River four nefuds of having flowed through, and Ten-Watershed River Crossing Ku Buqi desert, the Inner Mongol, the downstream of Heihe river Badanjilin Desert etc. of having flowed through.River, this desert and have serious sand damage problem and unique ecological environment characteristic because of its desert of flowing through.First, sand is constantly inputted in desert, riverfront under wind-force effect in the river of flowing through, and causes river to stop up, and migrates, and the harm such as atrophy and Breach and diversion, make underwater bed dry, ecological degradation.A large amount of silt is taken to ，Wei downstream, downstream by river and has carried a large amount of husky sources, has increased downstream sand damage danger occurs, another aspect sand is piled up at underwater bed, lifting riverbed, forms danger such as " hanging rivers ", and human lives and industrial and agricultural production are caused to great risk.And the river water erosion to riverbank for a long time has further aggravated the destruction on riverbank.Desert area is because environment is arduous, and wind-sand activity is frequent, and top layer, sand dune lacks, and radiation is strong, and evaporation is large, and vegetation is difficult to a series of conditions such as survival makes desert area environment severe, and ecology fragility is not suitable for human lives and produces very much.Along with river ecological protection, the sternness of problems such as control of desert and downstream " hanging rivers ", the research of administering about riverbank, river, desert sand damage has very important significance.

Utility model content

The purpose of this utility model is for problems of the prior art, and riverbank, river, a kind of desert sand damage governing system is provided.

Riverbank, river, a kind of desert of the present utility model sand damage governing system, comprises water lift drip irrigation system and admittedly hinders the raw vegetation of intrasystem sand for it provides solar photovoltaic generation system, the drift sand of power admittedly to hinder system and is planted in drift sand; Described water lift drip irrigation system comprises extracting water facility, drip irrigation facility, is placed in the reservoir of below ground; Described drift sand resistance system admittedly comprises the forward position sand-proof net and the sand prevention lattice that are located at two sides, river standing in away from both sides, river.

In order to stop effectively in time forward position dust storm, described forward position sand-proof net be arranged in parallel.

Described forward position sand-proof net is highly 1～2m on the ground.

Described sand prevention lattice are highly 10～50cm on the ground.

Described sand prevention lattice area is 1～2m ².

The relative prior art of the utility model has the following advantages:

1, the utility model arranges drift sand and admittedly hinders system and can effectively tackle the sand in desert; prevent that it from entering river; the problem that has fundamentally solved a large amount of sands source, river, desert, protection downstream river is avoided the threats such as sand damage and " hanging river ", safeguards river ecological safety.

2, the utility model, by planting and water lift drip irrigation, has reduced wind-sand activity effectively, and exposed husky source is reduced, and has effectively prevented sand, makes desert become vegetation, fundamentally reverses desertification.

3, the utility model combines the technology such as sand-prevention engineering, plant sand prevention, drip irrigation, solar energy effectively, suits measures to local conditions, and utilizes river and the desert energy, has effectively reached riverfront control of desert, and protection desert river ecological, improves region environment.

4, the utility model is suited measures to local conditions, and has fundamentally administered sand damage, has protected ecology, environmental protection, and sustainable, there is extraordinary reference popularizing action.

The specific embodiment

Below in conjunction with accompanying drawing, riverbank, river, a kind of desert of the present utility model sand damage governing system is described in further detail.

Riverbank, river, a kind of desert sand damage governing system as shown in Figures 1 to 4, comprises water lift drip irrigation system and admittedly hinders the raw vegetation of intrasystem sand for it provides solar photovoltaic generation system 9, the drift sand of power admittedly to hinder system and is planted in drift sand; Water lift drip irrigation system comprises extracting water facility 8, drip irrigation facility 10, is placed in the reservoir 5 of below ground; Drift sand resistance system admittedly comprises the forward position sand-proof net 2 and the sand prevention lattice 7 that are located at two sides, river standing in away from 6 both sides, river; Forward position sand-proof net 2 be arranged in parallel; Forward position sand-proof net 2 is highly 1～2m on the ground; Sand prevention lattice 7 are highly 10～50cm on the ground, and area is 1～2m ².

Water lift drip irrigation system comprises extracting water facility 8, drip irrigation facility 10, is placed in reservoir 5 and drip irrigation pipe 4 on desert, reservoir 5 is mainly Water storage, by extracting water facility 8, from the reservoir of lowest part, be passed to the reservoir of higher height, and the reservoir of every layer is passed to every place on sand dune 3 by drip irrigation pipe 4, and whole experimentation provides electric power by photovoltaic generation.

Specific implementation process mainly comprise following some:

Step 1: water lift drip irrigation system is set.No. 1, river bank reservoir 5 is first set, river is introduced, reservoir 5 plays precipitated impurities, stores the effect of water, and reservoir is comprised of impervious material and cement concrete, plays anti-sealing side and oozes and evaporation, and its specification is 5m * 5m * 5m.Set gradually again No. 2 reservoirs and No. 3 reservoirs, according to sand prevention size, can arrange No. 4 No. 5 and wait reservoir.Then arrange drip irrigation facility 10, drip irrigation facility 10 guarantees at least 1 delivery port of each sand prevention lattice 7 the inside (in every square metre of area) distribution.And then solar photovoltaic generation system 9 is set, and select more smooth place to set up, and communicate with drip irrigation facility 10, power is provided.

Step 2: drift sand is set and admittedly hinders system.One side in main air side first arranges, forefront is probably apart from 500 m left and right, river bank, according to wind-force power, the parallel forward position sand-proof net 2 in 2～4 roads can be set, by nylon fibers material, formed, by first, plugging in pricker 1 is fixed on the ground, it is height 1.5 m on the ground, play the husky effect of resistance of keeping out the wind, distance 40 m left and right between per pass; Within string Sand-fixation net grid is set again, height 20 cm on the ground, undergroundly fix second and plug in pricker 11 height 20 cm, grid specification is 1m * 1m.

Step 3: planting plants.Husky raw vegetation in plantation in string sand prevention grid, with sacsaoul, red building, the psammophytess such as white thorn are excellent.By water lift drip irrigation system, for it, provide water.At planting plants in May, before plantation, first water two days, guarantee pouring in 6 hours every day, then plantation, watered once every two days after plantation again, until germinate, then reduce to water number of times, within four days, water once.
