科学地识别区域水生态空间并分析其分布特征对水生态空间的规划和洪涝灾害等水生态问题的调控具有重要意义。以湖南省临澧县为研究区
构建水生态空间分类体系
借助GIS及RS平台
识别区域显性水生态空间
可视化水源涵养、水土保持、洪水调蓄3种隐性水生态空间
定量分析各水生态空间分布特征
并将整合的显、隐性水生态空间与土地利用现状图叠加分析。结果表明: (1)显性水生态空间占临澧县总面积的4.73%
以点状、斑块状、带状及枝状分布于县域
处于低海拔、较缓坡区; (2)隐性水生态空间面积占比为49.97%
少于水源涵养、水土保持和洪水调蓄空间面积占比总和69.68%
三者分别占比15.44%
38.07%
16.17%
均呈现"小集中、大分散"的特征
识别结果直观地反映了维护区域水生态安全的空间分布特征; (3)水生态空间占临澧县总面积的49.99%
主要分布于道水、澧水及其支流周边区域
中小型水库区域呈斑块散布; (4)水生态空间中的耕地和建设用地所占比例分别为44.40%
21.19%
表明水生态空间与人类活动剧烈的非生态用地类型存在重叠空间。研究结果揭示了临澧县土地利用现状与水生态空间存在冲突
后期可重新规划水生态空间中的非生态用地类型
以期高效保护水生态空间和规避水生态安全问题。
Scientifically identifying regional hydro-ecological space and analyzing its distribution characteristics were of great significance to the planning of hydro-ecological space and the regulation of hydro-ecological space problems such as flood disasters. Taking Linli County
Hunan Province
as the research area
this study constructed a classification system of hydro-ecological space with the help of GIS and RS platform
regional explicit hydro-ecological space was identified
and the three types of recessive hydro-ecological spaces of regional water conservation
soil and water conservation and flood regulation were visualized. And the distribution characteristics of each water ecological space were quantitatively analyzed. Finally
explicit and recessive hydro-ecological spaces that were integrated were superposed with current land use map for analysis. The results showed that: (1) Explicit hydro-ecological space occupied 4.73% of total area of Linli County
which distributed in dots
patches
bands and branches in the county
and located in a low-altitude
relatively gentle slope area. (2) The area of recessive hydro-ecological space accounted for 49.97%
which was less than 69.68% of the total area of water conservation
soil and water conservation and flood regulation space
which accounted for 15.44%
38.07% and 16.17%
respectively
showing the characteristics of "small concentration and large dispersion". The identification results intuitively reflected spatial distribution characteristics of maintaining regional hydro-ecological security. (3) Hydro-ecological space accounted for 49.99% of total area of Linli County
which mainly distributed in the areas around Daoshui
Lishui and its tributaries. Small and medium-sized reservoirs were scattered in patches. (4) The proportions of cultivated land and construction land in hydro-ecological space were 44.40% and 21.19%
respectively
indicating that there was an overlapping space between hydro-ecological space and non-ecological land types with intensive human activities. This study revealed that current land use was in conflict with the hydro-ecological space in Linli County. The non-ecological land types in the hydro-ecological space could be re-planned later
in order to efficiently protect hydro-ecological space and avoid safety issues of hydro-ecological.
