摘要

不透水表面扩张对城市生态系统的过程、功能、服务有显著影响

研究其演变规律对城市发展有重要意义。以南京市为研究区

基于2000—2020年土地利用数据

采用空间梯度分析与景观格局分析相结合的方法

沿城市中心向外设置等距辐射状梯度带

分析不透水表面时空分布和梯度变化特征

同时建立沿江、跨江样带

研究不透水表面扩张规模与方向演变背后的驱动机制

最终为南京市景观格局优化提供政策依据。结果表明:(1)不透水表面景观优势度沿梯度带逐渐降低

城市中心不透水表面高度集聚

外围城区是扩张的重点区域

耕地、林地、水域等景观面积缩减严重

景观格局变化剧烈

城郊区域保持低速稳定扩张。(2)地形地貌与河流水系显著影响不透水表面扩张方向

政策规划也起到一定的作用

经济发展、人口增长、产业结构优化影响不透水表面扩张规模。(3)南京市应从改善城市生活空间、转变城市发展模式、控制城市扩张规模3个方面对城市景观格局进行优化。

Abstract

Impervious surface expansion has a prominent impact on the process

function and service of urban ecosystem

so exploring its variation is of great significance to urban development. Based on the land use data from 2000 to 2020 in Nanjing

we integrated landscape spatial gradient analysis and pattern analysis method

setting radial gradient zones around the downtown by expanding outward at equal distances to analyze the spatial and temporal distribution and gradient characteristics of impervious surface. Meanwhile

the transects along and across the Yangtze River were set to analyze the driving forces behind the expansion scale and direction variation of impervious surface. It could provide policy suggestions for the landscape pattern optimization of Nanjing. Results showed that: (1) Impervious surface landscape dominance showed a downward trend along the gradient zone. The urban center was highly concentrated with well-shaped impervious surface. The peripheral urban area was the key regions of impervious surface expansion

accompanied with the reduction of arable land

forest land

water body and other natural landscape

so the landscape pattern of this area changed drastically. The suburban area impervious surface maintained slow and steady expansion. (2) Topography and river system significantly affected the expansion direction of impervious surface

planning policy would play a certain regulatory role. Economic development

population growth and industrial structure adjustment and optimization affected the expansion scale of impervious surface. (3) Nanjing should optimize the urban landscape pattern from three aspects improving the urban living space

transforming the mode of urban development and controlling the urban expansion.
