Abstract

The invention is based on a network platform and is combined with a network database and WebGIS technology. Field development processes of planthoppers at different places are displayed in real time. Pictures of planthoppers with different insect states and different instars are superposed on a vector map for displying field development states of the planthoppers at different places. Furthermore a planthopper emergence data is forecasted according to the vector map. A reference can be supplied for macro-level policy-making and early warning for large-area planthopper, and furthermore the WdbGIS-based planthopper development process display system helps to correct investigation forcast errors at different places. The WdbGIS-based planthopper development process display system simulates, investigates and summarizes the insect states and instars of the planthoppers at different places through the network platform. Furthermore the WdbGIS-based planthopper development process display system adds the insect states and instars of the planthoppers into a database which is connected with a space database (administrative map). The WdbGIS-based planthopper development process display system displays the planthopper development processes at different places in a point manner through combining with latitude and longitude coordinates, thereby realizing a better visual and vivid effect. The WdbGIS-based planthopper development process display system can be displayed through the network platform (including a mobile network). The invention discloses a realizing principle of the WdbGIS-based planthopper development process display system and a method thereof.

Description

The plant hopper developmental process display systems of sing on web GIS and method

One, technical field

The invention belongs to Prognosis of Agricultural Insect Pests technical field, be specifically related to a kind of technology and the method for applying WebGIS real-time exhibition plant hopper developmental process.

Two, background technology

Plant hopper is important agricultural pests, the various crop such as hazard rice, corn, and propagates various crop virus disease, the control of plant hopper is mainly contained to the methods such as cultural control, physical control, chemical prevention, all needs to be grasped the developmental process of forecast plant hopper.

For a long time, various places are all estimated according to the field experience of plant protection technology personnel the field developmental process of plant hopper and emergence period early warning, and report higher level operating officer unit by letter, Email, then aggregate tabular displaying through it.The impact of experience early warning human factor is large, and random strong, be easy to occur error, and the information transmission of letter, lettergram mode also result in the waste of a large amount of manpower, energy, be difficult to reflect field conditions in time, the early warning of large scale scope is not known where to begin especially.

GIS technology is domestic existing part application on pest forecast, but is mostly by software development prog charts such as Surfer, ArcGIS, MapInfo, and then issues.These softwares need certain financial support, and software operation is relative to Forecast Techniques personnel, and step is numerous, use complexity, a large amount of time energy be spent, in most of the cases, these figures are only the analysis demonstrations in later stage, cannot be used for monitoring and the early warning of insect.

The few thing of Forecast Techniques personnel people is many now, investigation sample amount is little, gap between generations, technical merit has a declining tendency, the robotization that this invention application WebGIS technology achieves large scale scope plant hopper developmental process is intuitively shown, for plant hopper macroscopical early warning, crop allocation and control its harm and have extremely important value.

Three, summary of the invention

1, goal of the invention

Be intended to invent a kind of technology applying WebGIS platform real-time exhibition field plant hopper developmental process, more intuitively can reflect the development condition of field plant hopper, scientific basis is provided for working out scientific and reasonable plant hopper its comprehensive prevention countermeasures, for large-scale macro-level policy-making provides reference, more accurately, in time, the emergence period of prediction plant hopper, correct the human error in investigation work, improve and observe and predict accuracy rate, thus the robotization early warning realizing plant hopper precisely controls.

2, technical scheme

This method application is based on Apache+PHP+MySql+MapServer software environment, the plant hopper of real time modelling is grown worm state, worm age after field investigation data correction, be saved in database, tabular shows the developmental process of plant hopper day by day that is current and forecast, and by the ephemeral data table that comprises various places latitude and longitude coordinates information and ovf file set up new layer, respectively grow the picture file in worm state, worm age in conjunction with plant hopper, in WebGIS, show being supplied to user.

3, beneficial effect

Method of the present invention compared with prior art, has following several advantages: (1) is automatical and efficient, and exploded view is generated automatically by server end, without the need to manual manufacture; (2) by force ageing, can reflect in real time and forecast the developmental process of field, various places plant hopper; (3) instruct wide, can be used for macroscopical trend analysis, instruct large-scale plant hopper prediction and protection, get rid of the impact of human factor, reduce prediction error; (4) visual pattern, very clear, and can be used for the analysis of plant hopper pests occurrence rule; (5) specifically lively, simple to operation.

Four, accompanying drawing explanation

Various places, Fig. 1 Jiangsu Province are plant hopper worm state, worm age day by day

Various places, Fig. 2 Jiangsu Province plant hopper developmental process is shown

Various places, Fig. 3 Jiangsu Province generation plant hopper adult is contained and sends out peak period prognostic chart

Fig. 4 is according to system flowchart of the present invention

Fig. 5 is according to system architecture diagram of the present invention

Five, embodiment

The plant hopper developmental process display systems of a kind of sing on web GIS that the present invention proposes and method, be described as follows with example by reference to the accompanying drawings.Below implement for illustration of the present invention, but be not used for limiting the scope of the invention.

This method is by the network platform, and user can directly run, by simply going up net operation, by client computer, smart mobile phone or other mobile device displaying live view.

Various places plant hopper worm state, the worm of simulation in 2012 and field investigation are as shown in table 1 for age, after revising, real-time exhibition various places are plant hopper developmental process (Fig. 1) day by day, and show with WebGIS (Fig. 2), also can forecast the emergence period of a certain concrete worm state of plant hopper simultaneously and show (Fig. 3) with different depth color polygon.
