The Design And Implementation Of Integrated Information System Of Agro-Ecological Environment In Jilin Province

Taking Jilin province as study area,with the supporting of meteorological data in 1976 ~ 2017,42(accumulated temperature and precipitation),distribution of soil type and soil properties,remote sensing images and DEM,and a variety of geographical spatial data,the jilin province agriculture ecological environment comprehensive information database is established.On this basis,the Integrated Information System of Agro-Ecological Environment in Jilin Province was designed.The evaluation criteria of accumulated temperature,precipitation,soil fertility and ground slope were established by referring to the previous research results,combining with the actual situation of the research area and national policies.According to the evaluation criteria,three single factor evaluation models and a comprehensive evaluation model are established.The system takes C# as the development language and ArcEngine10.1 as the secondary development platform,which is realized through VPL(visual programming language)and GIS component development method.The system realizes the functions of map browsing,data management,spatial interpolation,ecological suitability evaluation and comprehensive information query.Users can query not only 42 years of meteorological data,terrain,soil distribution and soil composition of the area,but also can obtain accumulated temperature,precipitation,soil fertility,and ground slope under the influence of the agricultural ecological suitability in spatial distribution.According to the results of ecological suitability evaluation,local planting Suggestions were obtained,including seed selection and fertilization.
