摘要
通过选取生物多样性保护、水源涵养、洪水调蓄、土地利用、土壤保持等5个评价因子与权重确定,结合镇江市具体地理位置及生态功能区划技术规程,应用Landsat TM遥感数据,对镇江市生态服务功能重要性进行了评价分区。结果表明:镇江市生态服务功能极重要区在九华山、圌山、五洲山,内江、西麓水库等地区,重要区分布在山体、水域周围,较重要区分布在岗地地区,生态服务功能不重要区分布在城区、及一些沟谷地区。
Based on five factors of biological variety protection,water conservation,flood pondage,soil utilization,soil conservation and weight determination,the importance distribution of ecological service function of Zhenjiang City was assessed in this paper by combination of specific geographical location and technological regulations of ecological function for Zhenjiang City.On the basis of Landsat TM data,the result indicated that：the very important area of ecological service function is distributed in areas of Jiuhua Mountain,shan Mountain,Wuzhou Mountain,Neijiang and area of Xilu catchment.The importance area is distributed around the areas of mountain and water catchments.The moderate importance area is distributed in hillock area and the less importance area is in urban area.
