Study Of Agricultural Climate Resources Information System In Fujian Province

Agricultural climate resources is 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.Firstly, having analyzed the present research situation on agricultural climate resources by GIS at home and abroad, this thesis illustrates the importance of establishing agricultural climate resources information system. Secondly, basing on developmental and integrative environment of Arc View GIS software, as well as developmental languages (Avenue and VB), we design agricultural climate resources information system in Fujian province with friendly and practical graphic user interface, together with comparatively perfect functions. Finally, supported by FJACRIS, based on Fujian province fundamental geographic data and agricultural climate resources database on 71 weather stations, relied on mathematic analysis techniques (such as multiple statistical analysis,fuzzy mathematics etc), a group of models are established to reckon the agricultural climate resources on small grids 41 indexes of agricultural climate resources are reckoned to the small grids that are 0.004 longitude multiplied by 0.004 latitude. The spatial distributing rules of agricultural climate resources in Fujian province are fully revealed. On this basis, comparatively meticulous, accurate and reliable fuzzy comprehensive assessment of agricultural climate system function, comprehensive agricultural climate regionalization as well as thematic one are completed.
