耦合MOP-PLUS模型的库车市LUCC趋势与景观生态安全评价
LUCC Trend and Landscape Ecological Security Evaluation in Kucha City through Coupled MOP-PLUS Model
摘要
Abstract
Aiming to explore the spatial and temporal evolution of urban landscape ecological security in typi-cal oasis city in arid areas,four scenarios including economy,ecology,landscape ecological security and sus-tainability(MOP)were used to predict land use/cover change(LUCC)trend,and to evaluate landscape eco-logical security in 2030,which could help ease the tension between urban construction and development and ec-ological environment protection.Based on the land use data from 1990 to 2020,methods such as remote sens-ing and geographic information system grid were used to construct the landscape ecological security evaluation model in order to demonstrate the landscape ecological security spatial distribution characteristics and change trends in Kucha City over the past 30 years,and to predict spatial and temporal evolution patterns of landscape ecological security in Kucha City in 2030 through coupled MOP-PLUS model.The results showed that from 1990 to 2020,the areas of cultivated land,woodland and construction land in the research areas showed an overall increasing trend,while the areas of grassland and water showed an overall decreasing trend,and land type conversion mainly focused on cultivated land,grassland and unused land.The spatial clustering status of landscape ecological security value(ESI)was obvious,but the degree of clustering decreased,and the landscape ecological security level was dominated by medium,higher and high ESI,which accounted for 60.15%-64.87%of the total area of the study area.Compared to 2020,the changes in ESI under the four scenari-os in 2030 were relatively large,mainly concentrated in the southern population gathering areas.关键词
