【摘要】：以河南省为例,应用基于纵向集成的改进假设抽取法,对该区域三次产业和八大部门的水资源消耗及转移状况进行量化分析,由分析结果可知:农业和基础工业是河南省的主要水资源净输出部门,轻工业、高科技工业和建筑业是主要的净输入部门。河南省用水关联性较强产业部门包括农业-轻工业、农业-高科技工业、基础工业-高科技工业以及农业-基础工业。对不同尺度的用水关联成果进行了分析,分析结果表明:不同分析尺度的纵向集成消耗总量是相等的,且与其直接消耗总量相同;用水关联具有非线性的尺度效应,不能通过线性运算实现不同尺度关联效应的转换;分析尺度越小,分类越细化,内部效应越低,系统中流动转移的水量就越多,反之则相反。研究成果可为区域产业结构调整和水资源管理政策的制定提供参考。
[Abstract]:Taking Henan Province as an example, using the improved hypothesis extraction method based on vertical integration, the water resources consumption and transfer status of the three industry and the eight major sectors in the region are quantified. The results show that agriculture and basic industry are the main net output departments of water resources in Henan Province, the light industry, the high-tech industry and the construction industry are the main ones. The strong industrial sectors of water use in Henan province include agriculture light industry, agricultural high-tech industry, basic industry, high-tech industry and agriculture basic industry. The results of different scales of water use correlation are analyzed. The results show that the total amount of vertical integration consumption of different analytical scales is equal, and it is straight. The total amount of consumption is the same; the water association has nonlinear scale effect and can not realize the transformation of the correlation effect of different scales by linear operation. The smaller the analysis scale, the more refined the classification, the lower the internal effect, the more flow and transfer of water in the system, on the contrary, the research results can be the adjustment of the regional industrial structure and the management of water resources. Policy formulation provides reference.
