山区土地利用变化强度与稳定性诊断研究
Diagnostic study on the intensity and stability of land use changes in mountainous area
摘要
Abstract
In order to analyze the characteristics of land use change in mountainous areas,rational use and protection of land resources.In this study,Dehua County of Fujian Province,an area with high urbanization in the mountainous region,is taken as an example.The remote sensing interpretation technology and multi-level land use change intensity analysis are adopted to identify the intensity and stability of land use changes in 1986,2001,and 2020,and explore their changing patterns and driving mechanisms.The results show that:1)The overall change intensity of land use in the early stage of urbanisation(1986-2001)is greater than that in the middle and late stage(2001-2017),and the change intensity of land use from valleys to low mountains to Zhongshan gradually decreases.2)The changes in construction land,waters,bare land and grass are relatively active during the study period,while the changes in forest land remain relatively stable.The transfer of cultivated land shows both activity and passivity,and the intensity of land type transfer is affected by topography.3)The increase of woodland mainly comes from grassland.The conversion process of"grassland-forestland"is characterized by a stable and systematic tendency conversion model;the occupation of cultivated land,bare land and waters for construction land is systematic;and the land change model with a large transfer area is not necessarily characterized by stability or systematic change.Land conversion patterns such as"forest land-construction land"and"grassland-forest land"are affected by topography.4)The urbanization process and development strategy are the key factors affecting the scale and speed of land use change.The study suggests that in the future,the layout of arable land in mountainous areas needs to conform to social development and population distribution.The balance of the entry and exit of arable land should adhere to a broken dialectical thinking,while the linkage of urban and rural construction land should establish the concept of"human-land linkage".关键词
