| 摘 要： | 针对行政单元生态承载力评价不能精细反映区域内部生态状况的差异和局部细节特征的问题，难以满足精细管控生态承载力的需要，本文提出了格网化生态承载力评价方法。基于生态足迹模型，结合人口空间分布模型，借助GIS空间分析技术，从格网角度对生态足迹和生态承载力进行定量估算与空间格局分析，并以衡水市为例进行试验验证。结果表明，格网尺度生态承载力评价方法与区域生态承载力评价方法相比更符合真实情况。从格网尺度看，衡水市生态足迹分布圈层特点，生态承载力呈离散分布特征。生态赤字状况表现出明显的异质性，沿滏东排河和滏阳河两侧呈条带状分布。衡水市大部分地区处于生态赤字临界状态，生态状况亟须得到保护。

| Abstract: | Aiming at the problem that the evaluation of regional ecological carrying capacity of administrative units can not reflect the differences of ecological conditions and local details of the administrative units, and can not meet the needs of the construction of the control mechanism of differentiated ecological carrying capacity, the paper proposes an evaluation method of ecological footprint model. Based on the ecological footprint model, combined with the population spatial distribution model, GIS spatial analysis technology is used to quantitatively estimate the demand and supply of ecological carrying capacity and ecological footprint from the grid scale and analyzes the spatial pattern. Hengshui city is used as an example to verify the experiment. The results show that the grid scale ecological carrying capacity evaluation method is more consistent with the real situation than the regional ecological carrying capacity evaluation method. From the grid scale, the ecological footprint distribution presents the characteristics of the circle; the ecological carrying capacity presents discrete distribution characteristics. The situation of ecological deficit shows obvious heterogeneity, with banded distribution along the Fudong Paihe River and Fuyang River. Most areas of Hengshui city are in a critical state of ecological deficit, and the ecological status needs to be protected. |
