基于生态系统服务价值的城市土地空间分区优化研究——以上海市宝山区为例

以上海市宝山区为例，在区域生态系统服务价值空间格局分析的基础上，识别出生态系统服务价值敏感区域，并采用最小累积阻力模型开展基于生态系统服务价值保护的城市土地空间分区优化研究。结果显示：①宝山区土地利用类型空间梯度分异显著，呈现出由东南部向西北方向辐射状递增的特征；②区域可划分为重点保育区（57.22km²）、一般保护区（123.32km²）、生态建设区（88.5km²）与优化开发区（24.67km²），建议结合基础条件及控制要求开展差异化发展；③最小累积阻力模型与生态系统服务价值相结合，应用于城市土地空间分区优化研究具有较强的适用性与可操作性。

Urban Land-Use Zoning Based on The Value Assessment of Ecosystem Services for Baoshan District, Shanghai

Baoshan district in Shanghai was examined by mapping and assessing ecosystem service values and analyzing spatial patterns in these across the district. Sensitive areas of land use and cover were then identified. We chose the minimum cumulative resistance model to conduct spacedividing research for ecosystem service values based on a combination of ecosystem service value assessment models. We found that the ecosystem service value of Baoshan district shows spatial gradient differentiation, radial incremental features from the southeast to the northwest of the study area, and corresponds with land use patterns across the district. The total area can be divided into four parts: conservation, general protection, ecological a construction zone and optimized development zone, the areas of which were 57.22km², 123.32km², 88.5km² and 24.67km², respectively. We suggest alternative development plans so as to fully take advantage of the special conditions of each area. The minimum cumulative resistance model has strong applicability and operability in the space partition study of ecosystem service values combined with the ecosystem service value assessment. This approach will stimulate further research into grading standards and land expansion resistance coefficients.
