Spatio-temporal characteristics and trend prediction of land-use change in Yangling Demonstration Zone
摘要
Abstract
As an agricultural high-tech demonstration city,high-efficient land-use in Yangling Demonstration Zone is the prerequisite for playing an exemplary role of modern agricultural devel-opment.Therefore,the study of current land-use status and existing issues in Yangling Demon-stration Zone could provide a critical reference for the future land-use planning.In this study,the spatial distribution patterns of land-use types in Yangling Demonstration Zone were obtained by analyzing Landsat data in 2000,2010 and 2020.The spatio-temporal characteristics from 2000 to 2020 were analyzed by quantitative indicators,such as land-use information entropy,single dy-namic degree and transfer matrix.The social statistical data from 2000 to 2020 were collected to qualitatively analyze the driving factors of land-use changes.The CA-Markov model was estab-lished to predict the land-use changes in the study area in 2030 and 2040.The results showed that:① the area of cropland in Yangling decreased significantly from 2000 to 2020,with the area of building land and vegetation increasing;② the conversion of land-use types was diverse,and the majority changes were cropland to building land and vegetation.The spatial distribution of landscape types became more balanced,indicating a harmonized development of Yangling;③ the main driving forces of land-use change were population,gross product and overall plan for land use in demonstration zone;④ the land-use changes in the Yangling Demonstration Zone over the next 20 years will be less significant and indicate a stable landscape pattern.关键词
