摘要: 以整个重庆市域为研究对象,利用回归模型结合地理信息系统空间插值方法进行重庆市各区县的农业气候资源要素数据模拟与采集,两种方法的组合在一定程度上可提高气候资源要素评价数据的精确性,然后利用数学综合评价指数对重庆市各区县农业气候资源优度进行评价。结果表明,重庆市农业气候资源的综合满意度总体水平较高,各区县市间的差异不大,但各单项农业气候资源的匹配性不好。研究结果可为当地合理利用气候资源进行农业生产规划与布局提供参考。

Abstract: Taking Chongqing City as a case study,the data for key factors of agro-climatic resources in the different counties of Chongqing was collected and simulated,by using the multi-regression analysis and spatial interpolation in GIS.The grade evaluation of agro-climatic resources was made with the integrated assessment method.The results indicated that there were not significant differences on the integrated satisfaction degree of agro-climatic resources among different counties in Chongqing,but the matching of the individual factor of agro-climatic resources was not good.The results would provide a basis for the agricultural planning in utilization of agro-climatic resources.
