摘要:

该文利用数学回归模型和地理信息系统空间插值两种方法的组合获取重庆市各区县农业气候资源评价的原始数据,然后采用物元可拓理论和熵权法构建重庆农业气候资源的综合评判模型,对各区县农业气候资源进行综合评价。结果表明:重庆市农业气候资源具有一定的相对优势,各区县之间差距不大,但各单项农业气候资源的匹配性存在一定不足。该文研究结果可为当地合理利用农业气候资源提供指导,实现区域农业的合理布局。

Abstract:

This paper uses combination of the two methods of mathematic regression model and geographic information system with space insert value and gains original data of various districts and counties in Chongqing City for agriculture metrological resources evaluation.Then it carries out comprehensive evaluation on agriculture metrological resources of various districts and counties,by adopting matter development theory and entropy right law to construct comprehensive evaluation model for agriculture metrological resources in Chongqing.The results indicate that agriculture metrological resources in Chongqing possess certain relative advantage.There are not many differences between various districts and counties.But there are deficiencies existing in the matching of single agriculture metrological resources.This research finding could provide guidance for rational utilization of local agriculture metrological resources,so as to realize rational distribution of regional agriculture.
