| 摘 要： | 对大连土壤侵蚀敏感性和蛇岛老铁山区综合敏感性进行了评价。土壤侵蚀敏感性评价结果表明:大连市中部地区和西北部小部分地区属于微度敏感;西部及东部地区属轻度敏感;北部与东北部大部分地区属于强度敏感。蛇岛老铁山自然生态系统老铁山区敏感性综合评价指数为5.5,九头山区敏感性综合评价指数为3.0,农田村落区敏感性综合评价指数为4.1。蛇岛老铁山自然生态系统老铁山区属重度敏感。

| Abstract: | An evaluation of soil erosion sensitivity and comprehensive one of Snake Island-Old Iron Mountain Nature Reserve sensitive areas in Dalian region were made.The results of soil erosion sensitivity showed that the middle area and a little of west-north area in Dalian is subordinate to tiny sensitivity;the west and east is subordinate to light sensitivity;north and must of east-north is subordinate to strong sensitivity.The sensitivity index of Old Iron Mountain area of the Snake Island-Old Iron Mountain nature ecosystem is 5.5;the sensitivity index of Nine Mild area is 3.0 and that of farm village area is 4.1.The sensitivity index of Snake Island-Old Iron Mountain Nature Reserve sensitive areas shows a strong sensitivity. |
