基于生态系统服务重要性的城镇优化管理——以福州沿海地区为例

城镇;建设用地;生态系统服务重要性;最小阻力模型;福州沿海地区
摘  要：
在RS与GIS技术支持下,选择研究区比较重要的生物多样性保护、土壤保持、水源涵养和洪水调蓄4个生态系统服务功能,对福州沿海地区生态系统服务功能进行综合评估,并采用最小累积阻力模型开展基于生态系统服务重要性的城镇建设用地空间分区优化研究。结果显示:(1)福州沿海地区生态系统服务重要性程度较高,极重要和重要区域的面积占总面积的66%,且空间差异明显,北部较高,南部较低;(2)研究区域可划分为适宜建设区(2 698.06km2)、限制建设区(1 345.06km2)、生态保护区(655.08km2)与重点生态保护区(459.92km2),建议结合区域实际情况开展差异化发展。

摘  要：
We selected four major ecosystem services such as biodiversity conservation,soil conservation,water conservation and flood storage to evaluate the importance of ecosystem services of Fuzhou coastal areas using RS and GIS techniques.We chose the minimum cumulative resistance model to conduct urban space dividing research based on a combination of ecosystem service importance assessment models.The results indicate that:(1)the ecosystem service importance of Fuzhou coastal areas is higher,the most important areas and regional area account for 66% of the total area,and the obvious spatial of ecosystem service importance is different,and the ecosystem service importance is high in the north and low in the south;(2)the total area can be divided into four parts:Suitability land for construction,restrictive land for construction,ecological conservation land and key ecological conservation land,the areas of which were 2 698.06km2,1 345.06km2,655.08km2 and 459.92km2,respectively.We suggest alternative development plans with respect to the actual conditions of each area.
