大运河河北段景观格局与气候调节功能时空演变及关联性分析
Space-time Evolution and Correlation Analysis of Landscape Pattern and Climate Regulation of Hebei Grand Canal
摘要
Abstract
As the longest man-made canal,the Beijing-Hangzhou Grand Canal runs from north to south and integrates ancient and modern times.It is a precious cultural heritage flowing in the land of Chi-na.With the rapid development of the towns along both sides of the Canal,it is of great significance to study their landscape pattern and climate regulation function for the construction of green and livable Grand Canal cultural belt and the goal of"double carbon".This paper selects the northern section of the Grand Canal from 1990 to 2020 as the research object,and quantitatively analyzes the landscape spatial heterogeneity changes of 21 counties in the study area by using landscape pattern index.Meanwhile,the IUEMS model is used to quantitatively assess the temporal and spatial distribution and changes of climate regulation service functions in the study area.The grey correlation model between landscape pattern index and climate regulation service function is constructed,and the correlation degree is analyzed.The results show that:(1)From 1990 to 2020,cultivated land is the main land use type,and the number of cultivated land patches decreases first and then increases,but the maximum patch index,patch density,patch edge density and aggregation degree have little change;(2)From 1990 to 2020,the average annual total energy consumption in most regions is 3.8～6.3kWh/a,accounting for 82.36%of the total area,and the climate regulation service function presents a wave change trend of first rising,then decreasing and then rising;(3)The correlation between the number of patches and the temperature regulation service function is the high-est,and the correlation degree is 0.7312.The correlation degrees in descending order are:The number of patches>Patch density>Aggregation index>Edge density>Maximum patch index.关键词
