基于遥感云计算的自然保护区土地利用时空演变及其生态环境效应
Spatial and temporal evolution of land use and its ecological and environmental effects in nature reserves based on the remote sensing cloud platform
摘要
Abstract
The study explores the spatial and temporal evolution characteristics of land use and ecological environmental effects in the nature reserve and its ecological environmental effects,aiming to provide scientific data and theoretical support for the related management authorities to carry out healthy development and scientific management of the reserve.Based on the AI Earth Earth Science Cloud Platform,the study explores the spatial and temporal evolution characteristics of land use and ecological environment effects in Xitianshan National Nature Reserve from 2000 to 2020 and analyzes the land use and ecological environment effects through the methods of land use change degree and the construction of remote sensing ecological index.The following results were obtained:① The land use changes in the reserve from 2000 to 2020 were that the area of grassland and snow and ice shrunk,and other land categories expanded.② The largest land use change in the protected area from 2000 to 2020 was farmland,followed by bare land,and the smallest was forest and grassland.③ The greenness and humidity of the protected area from 2000 to 2020 showed a continuous decrease,the dryness increased and then decreased,and the heat showed a continuous increasing trend.④ The area with poor ecological environment quality in the protected area from 2000 to 2020 showed a decreasing trend,and the proportion of the area with good and excellent ecological environment quality increased,and some of the area with good grade transformed into excellent grade,which resulted in the increase of area with excellent grade.The land change and ecological environment effect of the protected area in 2000-2020 was exhibited by the transformation from grassland to forest,which improved the ecological environment,the persistent expansion of bare land area and the potential ecological risk of farmland expansion;the reduction of snow and ice area contributed to the land in the short term to provide conditions for the development of vegetation,and it could improve the ecological environment;however,the persistent shrinkage of snow and ice area in the process of long-term development could seriously affect the healthy development of regional ecological environment.关键词
