西南山区资源环境承载力评价及协调发展分析——以云南省德宏州为例

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。

The Evaluation and Analysis of Coordinated Development on Resources and Environment Carrying Capacity in SouthwesternMountainous Area of China: A Case in Dehong Dai-Jingpo Autonomous Prefecture,Yunnan Province

Resources and environment carrying capacity is the basis for regional resources development and utilization as well as economic development strategy making and planning, which has already attracted large quantities of studies in academia. However, previous studies were inadequate in considering the connotation and restriction factors of resources and environment carrying capacity, and the evaluation indexes were not sufficiently connected with land planning (or regional planning). In the meantime, the indexes were treated in black box while neglecting the internal mechanism and coordinated development among systems. This study, took the Dehong Dai-Jingpo Autonomous Prefecture (Dehong Prefecture) in mountainous area of southwest China as a case. The paper evaluated the resources and environment carrying capacities of Dehong Prefecture and the five counties (cities) under its jurisdiction, and analyzed the mechanism and coordinated development of the nine sub-systems of resources and environment carrying capacity. The results showed that: 1) There is great regional difference of resources and environment carrying capacity in Dehong Prefecture. The resources and environment carrying capacities of Mangshi, Yingjiang and Longchuan counties are relatively high, and the carrying capacity of Lianghe County is at middle level, while the carrying capacity of Ruili is low. The five counties (cities) ranked as Mangshi > Yingjiang > Longchuan > Ruili > Lianghe in resources carrying capacity and ranked as Mangshi > Yingjiang > Longchuan > Ruili > Lianghe in environment carrying capacity. 2) The limitation analysis indicates that Ruili belongs to arable land-mineral resources limitation type, Mangshi and Longchuan belongs to mineral resources-geological environment limitation type, Lianghe belongs to arable land-urban construction limitation type, and Yingjiang belongs to water environment-geological environment limitation type. 3) Larger coupling relationship exists in resource-environmental system of Dehong Prefecture, especially the coordination degrees of urban construction system and geological environment system, forest resource system and atmospheric environment system, water resources and environment system, mineral resources system and atmospheric environment system are all above 0.96. The overall coordination degree of resources and environment in this region is up to 0.98.
