【摘要】：区域的产业发展与该区域的自然和社会经济因素密切相关,对于水网稠密地区,水环境承载力是影响产业结构和布局优化的重要自然因子之一。选择江苏省境内跨长江与淮河两大流域的典型水网密集区——扬州市北部沿湖(邵伯湖)地区为研究区,选取水网构成指数、水利设施调控指数和水质达标差距指数3个指标,评价研究区水环境承载能力,并探讨水环境承载力与不同产业结构的联系,为该地区产业结构布局和优化提供建议。结果表明研究区水环境承载力"高"、"较高"、"中等"、"较低"和"低"5个等级分别占研究区总面积的0.38%、21.74%、29.67%、13.65%和34.56%。根据研究区水环境承载力空间差异和水环境承载力与不同产业的联系,以选择生态涵养型产业为基本导向,以兼具开发适宜性和环境保护重要性为基本原则,提出应根据研究区水环境承载力水平不均衡的特点实施差别化的产业结构与布局方案,邵伯湖湖区及入湖河道下游等水环境承载力高和较高地区适宜发展特色水产与特色水禽的生态养殖业;沿湖、沿河及南部槐泗等水环境承载力中等地区适宜发展现代生态种植业及湖泊生态旅游业;河流中上游等水环境承载力低和较低地区适宜发展大宗农作物的种植。
[Abstract]:The natural and social economic factors of regional industrial development and the region is closely related to dense water network area, water environmental carrying capacity is one of the effects of industrial structure and layout optimization of the important natural factor. In Jiangsu province across the Yangtze River and Huaihe River Valley two typical dense area in northern Yangzhou Lake City area (Shao Bohu) the study area, selected water composition index, water conservancy facilities and water quality control index gap index 3 indicators, evaluation of region water environment carrying capacity, and to explore the water environment carrying capacity with the industrial structure, to provide suggestions for the optimization of regional industrial structure and layout. The results show that the study area of water environmental carrying capacity of "high", "high", "medium" and "low" and "low" 5 grades accounted for the total area of 0.38%, 21.74%, 29.67%, 13.65% and 34.56%. according to the water environmental carrying capacity of region spatial difference And the water environment carrying capacity associated with different industries, to select ecological conservation industry as the basic orientation, which has developed the suitability and importance of environmental protection as the basic principle, put forward according to the characteristics of water environmental carrying capacity level and balanced implementation of differentiated industrial structure and layout of the program, and the Shaobei Lake Lake the lake river water environmental carrying capacity of ecological aquaculture development characteristics and characteristics of waterfowl suitable for high and high area; the lake, along the river and south of the Huai Si and water environment carrying capacity of medium area suitable for the development of modern ecological planting ecological tourism and lake industry; low and low area suitable for the development of staple crops planting the carrying capacity of water the upper reaches of river environment.

【正文快照】： 在我国经济发展新常态的背景下,实现调结构和稳增长与诸多自然和经济社会因素密切相关。在水网稠密地区,水环境承载能力是影响产业选择的重要自然因子之一,而产业结构适宜性对水环境承载力亦有重要的反馈作用[1-3]。目前为止,水网密集地区水环境与产业选择研究尚处于探索阶段
