北盘江流域耕地景观格局时空演变
Temporal and spatial evolution of landscape patterns of cropland in Beipanjiang River Basin
摘要
Abstract
It is important to reveal the evolution process and trend of landscape pattern of cropland utilization in typical basins of karst mountainous areas in southwest China for their food security,sustainable development,and rural revitalization.This paper employed multi-period high-resolution remote sensing data,landscape pattern index,hotspot analysis,and other methods to study the temporal and spatial evolution law of the landscape pattern in the Beipanjiang River Basin from the perspectives of cropland utilization scale and cropland utilization pattern.The results show that the area of cropland in the basin shows a decreasing trend from 2010 to 2020,with a total decrease of 1 855.77 km2,accompanied by increasing fragmentation and decreasing aggregation.Spatially,there is a large-scale and morphologically complex aggregated distribution of cropland in the northwestern part of the basin and a small-scale and regular aggregated distribution in the southeastern part.Cropland in the basin is mainly developed into forests,gardens,and construction land,and smaller scale and larger complexity indicate a higher possibility of developing into other types of land.关键词
