The Agriculture Weather Resources And Its Information-based Research In Chongqing

Synopsis: Agricultural climate resources are the basic material and energy provided by nature for agricultural production to obtain products. It is also an important environmental factor of agricultural production. Agricultural climate resources assessment and agricultural climate regionalization is always an important task to regional development and territory rehabilitation.The domestic research in this aspect using traditional methods lasted a long time, which has made a great contribution to regional agricultural development. However, according to the demands of information age, the traditional research means, as well as the expression and application of fruits can not meet the reqirements in all aspects obviously. Having a wide foreground,the application of GIS technique provides an effective new way and new technique for analysing and developing of agricultural climate resources.The paper is based on the technologies of computer, especially GIS.On the one hand, this thesis detailedly researched the characteristic, the dimensional simulation, the quantitative evaluation, the crop distribution and the fully utilization of the agroclimatic resources in ChongQing region;On the other hand, this thesis especially discussed the development of functional subsystems about the informationalizing of Agroclimatic Resources.The aim of this thesis is assist the using and the thoroughly studying of regional Agroclimatic Resources base on the functional subsystems. The advancements are as follows:(1)Basing on the Arcview GIS, established the information system of agroclimatic resources in ChongQing region in the grid-system, It can offer information to the study on the fully utilizaion of agroclimatic resources in ChongQing region;(2)On the basis of information database, the part had a discussion on the dimensional distribution, quantitative evaluation ,the use full of agroclimatic resources and crop distribution in ChongQing region by making use of GIS and computer.ln the discussion,the fundermental unit of research is a kind of grid-system(5km×5km),which includes all related data of agroclimatic resources, administrative information(countyand town),numerical value of longitude and latitude,etc.In addition,during the quantifying analysis and assessment , using the index of ray ,heat and water and the integrated index(Cr),the configurable index(Cf),and effective index(Ce),the author not only analyzed and evaluated the differences of agroclimatic resources in ChongQing region,but made a comparison between it and some other districts in our land and made a conclusion on the position of ChongQing in the whole country.(3)Based on GIS ,this part discussed the informationizing management and utility of agroclimatic resources of ChongQing .This part mainly developed some functional subsystems by Avenue,such as data capturing,data processing and updating,data showing and visualizing,data querying and analyzing, information sharing and outputting and other aiding functions.The development of all these systems not only greatly improve the informationized management and analysis on the agroclimatic resources of ChongQing region.but also provide the theoretical and technological basis for constructing the aid-deciding system of the regional agroclimatic resources.
