【摘要】：区域农业水资源系统是与自然及人类活动紧密联系的复杂适应系统,不断与周围环境发生物质、能量和信息因素方面的交换和作用。以黑龙江省农垦红兴隆管理局12个农场为研究基点,运用主成分-相关分析法筛选评价指标,构建农业水资源恢复力评价指标体系,采用CRITIC法确定指标权重,结合可变模糊模型评价方法对其农业水资源系统恢复力进行评价,并利用ArcGIS技术对其进行分区,结果表明:双鸭山、八五三、北兴和八五二农场的农业水资源恢复力为Ⅱ级,饶河、二九一、五九七、红旗岭、友谊、江川、宝山和曙光的农业水资源恢复力为Ⅲ级。研究成果揭示了当地农业水资源系统力恢复情况,为农业水资源系统恢复力研究提供了一种新的研究模式。
[Abstract]:Regional agricultural water resources system is a complex adaptive system closely related to nature and human activities, which constantly exchanges and acts with the surrounding environment in terms of material, energy and information factors. Based on the 12 farms of Hongxinglong Administration of Agricultural Reclamation in Heilongjiang Province, this paper selects the evaluation indexes by principal component correlation analysis, constructs the evaluation index system of agricultural water resources resilience, determines the index weight by CRITIC method, evaluates the resilience of agricultural water resources system with variable fuzzy model evaluation method, and divides them by ArcGIS technology. the results show that Shuangyashan, 853, The resilience of agricultural water resources in Beixing and 852 farms was grade 鈪，
