Research On GIS Development And Application In New Rural Area Of Ningbo

The significant historic task of constructing socialism new rural areas advanced at the Fifth Plenary Session of the Party's 16th session is an important strategic policy of the Central Party Committee in order to solve the "rural, agricultural and fanners" issues in the new era. The new rural construction involves rural economic development, political construction, cultural development and social development and other aspects, which are inextricably linked with the construction of information. As an typical information technology for spatial data management and analysis, geographical information system (GIS) has been widely applied in the construction of rural area, including agricultural resources and ecological environmental management, agricultural production, rural planning, etc. However, at the present time, there are still many problems in GIS application for rural area. For example, it is hard to make comprehensive multi-factors analysis because the various systems established by different departments are independent, which makes both the data and software impossible to be shared; Little research on applying GIS to ecological environment and people's life of rural area has been done before; Construction fee of most GIS is high and there is few GIS products that are low-cost and easy-operated for general use of agriculture-related person. As the new rural construction goes on and the development of GIS application technology, it's quite necessary to research on these problems and related technologies.This paper carries out researches on the GIS development of the new rural construction in Ningbo, which includes research contents and results mainly on the following four aspects:1) The development of service-oriented GIS and service-sharing platform for the new rural construction of Ningbo. Based on researches on webservice-oriented geographical information sharing framework and the key technologies, this paper proposed how to design a new rural GIS for Ningbo, and developed a service-oriented geographical information sharing platform, which involves basic data service, common data processing service and management module. This platform is unified, cross-industries and cross-sectors, which makes it feasible to build professional GIS of different structures (B/S, C/S or M/S) on it. Under this situation, sharing and integration of resources are implemented.2) The development and applications of forest carbon stock calculation GIS in Ningbo. According to the characteristics of Ningbo forest ecosystems, the forest carbon stock model is established with quadrates analysis. Based on the data services provided by the sharing platform, the forest carbon stock GIS is developed with a C/S framework, which is then used to calculate the forest carbon stock of Ningbo and make an analysis. The result shows that the forest carbon stock of Ningbo amounts to 39.5TgC. It also indicates that the forest carbon stock in the western mountain areas is higher while it is lower in the central plains and eastern coastal areas.3) The development and applications of WebGIS for new rural construction evaluation in Ningbo. After making frequency analysis and theoretical analysis on the evaluation systems established by the domestic researchers on this issue, a new evaluation system made up of 5 first-class indexes and 27 second-class indexes is proposed to evaluate the new rural construction in Ningbo. Then, according to experts'marking, the weighted coefficient of each index is ascertained. A service-oriented evaluation WebGIS of new rural construction in Ningbo is developed based on this evaluation system, which thermally accesses the latest data provided by the service platform, and then updates the evaluation results on the web. Besides, if certain fields of statistical data are lost, the evaluation system will be modified automatically to fit the data.4) The development and application of mobile GIS in formula fertilization by soil testing. According to the actual situation of Ningbo, a fertilization model based on target output is proposed. Then a mobile GIS within M/S framework is development in formula fertilization by soil testing. The client of this GIS system includes three modules:real-time location by GPS, the query service of soil parameters and formula fertilization suggestion, which can be used to get the exact coordination of location, find out the soil parameters of location and figure out fertilization suggestion based on fertilizer type and target yield.104 soil samples are collected in the six eastern towns of Ninghai county. Based on these samples, a spatial distribution map of this area is made using Kriging interpolation method. The soil fertility information and fertilization suggestion based on the location of mobile client can be acquired immediately by the mobile GIS of formula fertilization by soil testing. It suggests that this mobile GIS is practical.
