摘要
基于"水-水文循环-生态环境变化"这一关键性农业生态系统环境要素,结合水的资源属性和水资源的高效利用内涵以及生产力水平、土地利用方式、种植结构、种植模式等几方面,选取构建川中丘陵区农业水资源高效利用综合分区指标体系(16个定量指标、4个定性指标),采用主成分分析和模糊C-均值聚类算法为区划方法,对川中丘陵区进行量化分区。分区结果表明,指标构建合理,分区方法得当,分区结果可靠,对于南方季节性干旱区进行农业水资源高效利用综合规划有较强的指导和借鉴作用。
Quantization partition can be done in Hilly Ground of Middle Sichuan using the method of principal component analysis and fuzzy C-means clustering algorithm,according to partitioning index system（quantitative indicators 16,qualitative indicators 4） of agricultural water resources utilization selecting and building in the light of the key elements of agricultural eco-system environment ＂Water-hydrological cycle-environmental changes＂,water resource properties and content of efficient use of water resources and Productivityproductivity,land use,planting structure and scale cultivation etc.The results of the partition shows that the quantization partition in Hilly Ground of Middle Sichuan has reasonable partitioning indicators,properly partitioning method and reliable partition results,providing a strong comprehensive planning guidance and reference to the arid area in southern seasonal agricultural water resources utilization.
