Design And Implementation Of Soil And Water Conservation Detection System Based On Soil Erosion Model

China,as the third largest country in the world,soil and water conservation work is particularly important.In the early stage,water conservation personnel needed to collect data in the field,then process data through mathematical software or GIS software,model and calculate soil erosion modulus to detect and evaluate soil erosion intensity.The whole process not only required proficiency in the use of various software,but also had low efficiency and automation.Nowadays,the establishment of hydrological stations in various regions makes the collection of hydrological data such as rainfall easy.Meanwhile,the emergence of various geographical equipment improves the efficiency of data collection,making many geographical data can be automatically collected and uploaded and stored through computer technology.With the development of geographical system technology and the accumulation of geographical data in various regions,it is of great significance to develop a set of soil and water conservation detection system for the automatic calculation of soil erosion modulus based on these data and technologies,which can be used for the detection and evaluation of soil erosion intensity.Therefore,based on the above background and requirements,this paper takes the CSLE model as the soil erosion model,designs and implements the soil and water conservation detection system for automatic calculation of soil erosion modulus,and uses GIS technology to project soil erosion modulus onto the map for hierarchical display for the detection and evaluation of soil erosion intensity.Aimed at making water conservation personnel through the system using a simple operation can be the target area of soil erosion modulus of automated calculation,calculation result will be projected on the map,can be more simple,intuitive observation of soil erosion intensity distribution,which is beneficial to the development of soil and water conservation work.The main work of this paper is summarized as follows:1.According to the requirements of users,this paper analyzes the requirements of soil and water conservation detection system.On the basis of demand analysis and CSLE model calculation requirements,the hierarchical architecture and functional modules of the whole system are designed.Then,the database design and file storage rules were designed according to the functional requirements.2.In this paper,the automatic processing of rainfall data in hydrological station is realized.According to the results of rainfall data processing,the rainfall erosivity factor was calculated by IDW interpolation and parallel interpolation.Finally,IDW parallel interpolation was used to calculate the rainfall erosivity of the whole province of Hubei.Under the resolution of 250m,the speed was improved 182 times.Based on this,the soil erosion modulus calculation of province,city and county was designed and realized.3.This paper provides a feasible implementation scheme,the data calculation is packaged into a computing task,through the way of computing task automatic calculation of soil erosion modulus,design and realize the scheduling of the computing task and the implementation of the calculation scheme.Finally,the calculation results are published by GeoServer,graded in different colors according to different values,and projected onto the map to show the regional soil erosion intensity.
