辽宁省生态系统敏感性评价

Ecosystem sensitivity assessment of Liaoning Province

根据辽宁主要生态环境问题的形成机制,分析了生态系统敏感性的区域分异规律,并对多种生态环境问题的敏感性进行了综合分析。结果表明,全省处于轻度至高度敏感区域,高度敏感区、中度敏感区、轻度敏感区分别占全省陆域面积的34.00%、62.66%和3.34%。高度敏感区分布在辽东山地丘陵、辽东半岛、辽西低山丘陵、辽西北、柳绕地区和大洼县。辽东山地丘陵、辽东半岛和辽西低山丘陵主要是土壤侵蚀高度敏感。辽西北和柳绕地区主要是土地沙漠化高度敏感。大洼县是土壤盐渍化高度敏感。

Based on the formation mechanisms of the main eco-environmental problems in Liaoning Province,this paper studied the regional differentiation patterns of ecosystem sensitivity,and analyzed the sensitivities of manifold eco-environmental problems in the Province.The results showed that the areas of high,medium,and low ecosystem sensitivity in the Province occupied 34%,62.66%,and 3.34 % of its total terrestrial area,respectively.High ecosystem sensitivity area mainly distributed in east Liaoning mountainous r...
