摘要
为把握两当县国土资源承载力的空间分异特征,从而立足本地资源,拓宽发展思路,加快山区发展,笔者分别对两当县水资源、土地资源、矿产资源承载力进行评价:(1)利用综合指标法对水资源和土地资源的承载力进行评价,水资源承载力结果为:高承载力主要分布在泰山、云屏、张家和兴化4个乡镇,中等承载力的乡镇有站儿巷、左家、西坡、鱼池、杨店、显龙和金洞;城关为低承载区。土地资源承载力结果为:高承载力主要分布在鱼池、云屏、泰山、金洞、站儿巷、显龙、杨店、兴化和左家这9个乡镇,中等承载力的有城关和西坡;张家为低承载区;(2)利用模糊综合评价法对矿产资源承载力进行评价,得出两当县矿产资源高承载力主要分布在云屏、站儿巷、鱼池、显龙、西坡、金洞、泰山、兴化这8个乡镇,张家、城关和杨店为中等承载力,左家为低承载区;(3)利用综合评价方法进行了两当县国土资源承载力评价。高承载力的乡镇为:泰山、云屏、张家和兴化,中等承载力的乡镇有鱼池、左家、杨店、显龙、站儿巷、西坡和金洞,城关属于低承载力区。
To study the spatial variation characteristics of land resources bearing capacity in LiangdangCounty, broaden the development idea and accelerate the development of mountain area, the authors evaluatedthe bearing capacity of water resources, land resources and mineral resources in Liangdang County. The resultsshowed that:(1) water resources and land resources were evaluated by comprehensive index method, the resultsof water resources evaluation showed that high bearing capacity were mainly distributed in Taishan, Yunping,Zhangjia and Xinghua, the medium bearing capacity area included Zhanerxiang, Zuojia, Xipo, Yuchi,Yangdian, Xianlong and Jindong, Chengguan was the low bearing capacity area; the results of land resourcebearing capacity showed that: high bearing capacity area was mainly distributed in Yuchi, Yunping, Taishan,Jindong, Zhanerxiang, Xianlong, Yangdian, Xinghua and Zuojia; the medium bearing capacity area includedChengguan and Xipo, and Zhangjia was the low bearing area;(2) mineral resources bearing capacity wasevaluated by fuzzy comprehensive evaluation method, the results showed that high bearing capacity area wasmainly distributed in Yunping, Zhanerxiang, Yuchi, Xianlong, Xipo, Jindong, Tai Shan and Xinghua; themedium capacity area included Zhangjia, Chengguan and Yangdian; Zuojia was the low bearing area;(3) landresources bearing capacity was conducted by comprehensive evaluation method, high bearing capacity wasmainly distributed in Taishan, Yunping, Zhangjia and Xinghua; the medium capacity area included Yuchi,Zuojia, Yangdian, Xianlong, Zhanerxiang, Xipo and Jindong; Chengguan was the low bearing capacity area.
