【摘要】：资源环境承载力评价是区域资源开发利用与经济发展战略决策及其规划的基础依据。当前学界对此进行了大量评价研究,评价指标方面尽管数量众多,但往往对资源环境内涵和制约因子考虑较少或者不够全面,指标与国土规划(或区域规划)衔接较少,同时其指标处理上常常只是简单地对系统做黑箱处理,缺乏对两个系统内部作用机制、协调发展状况的研究。论文以地处我国西南边疆山区的云南省德宏州为例,对德宏州及所辖5个县(市)资源环境承载力进行评价,并对资源环境承载力9个子系统的作用机制和协调发展状况进行评价分析。结果表明:1)德宏州资源环境承载力的区域差异较大,芒市、盈江县和陇川县为高等承载力,瑞丽市为中等承载力,梁河县为低等承载力,具体而言资源承载力大小排序为芒市盈江县陇川县瑞丽市梁河县,环境承载力大小排序为芒市盈江县陇川县瑞丽市梁河县;2)限制性分析结果显示,瑞丽市为耕地-矿产资源限制型,芒市和陇川县为矿产-地质环境限制型,梁河县为耕地-城镇建设限制型,盈江县为水环境-地质环境限制型;3)资源环境系统存在较大耦合关系,尤其是城镇建设用地系统与地质环境系统、森林资源系统与大气环境系统、水资源系统与水环境系统、矿产资源系统与大气环境系统等协调度均大于0.96,且各县(市)资源环境子系统间的协调度均高于0.98。
[Abstract]:The evaluation of the carrying capacity of resources and environment is the basis for the strategic decision and planning of regional resource development and economic development. At present, a large number of evaluation studies have been carried out in academic circles. Although there are a large number of evaluation indicators, they tend to consider less or less comprehensive resource and environmental connotations and constraints, and the indicators are less connected with land planning (or regional planning). At the same time, the index processing of the system is often simply black box processing, lack of internal mechanism of the two systems, coordination of the development of the research. Taking Dehong Prefecture, Yunnan Province, which is located in the mountainous area of southwest China, as an example, the paper evaluates the carrying capacity of resources and environment in Dehong Prefecture and five counties (cities) under its jurisdiction. The mechanism and coordinated development of 9 subsystems of carrying capacity of resources and environment are evaluated and analyzed. The results show that: 1) the regional difference of the carrying capacity of resources and environment in Dehong is great. Mango, Yingjiang and Longchuan are the higher carrying capacity, Ruili is the middle bearing capacity, and Lianghe is the low bearing capacity. Specifically, the order of carrying capacity of resources is Lianghe County, Ruili City, Longchuan County, Yingjiang County, Mango City, and Lianghe County, Ruili City, Longchuan County, Yingjiang County, Mango City. 2) the result of restriction analysis shows that Ruili city is restricted type of cultivated land and mineral resources, mango city and Longchuan county is restricted type of mineral and geological environment, Lianghe county is restricted type of cultivated land-town construction, Yingjiang county is limited type of water environment and geological environment; 3) there is a great coupling relationship between resource and environment system, especially between urban construction land system and geological environment system, forest resource system and atmosphere environment system, water resource system and water environment system. The coordination degree of mineral resources system and atmospheric environment system is more than 0.96, and the coordination degree of each county (city) resource environment subsystem is higher than 0.98.
