Study on the Land Use Pattern and Law of Ecological Environment Change in a Small Watershed in Hilly Areas in Southwest China
The change in land use pattern is closely related to human activities and natural evolution,which is of great significance to the harmony between human and nature.The Anju District of Suining City that located in the Qiongjiang River Basin was chosen as the research object in this paper.With the remote sensing technology and geographic information system,land use pattern and law of ecological environment change in the Anju District of Suining City was studied according to the transfer matrix of land use.The results showed that land use increased first and then slowed down from 2010 to 2019.The change in urban land use was remarkable,and land was mainly transferred from cultivated land.Land use in the urban area of the Anju District was highly dynamic,with little change in the other four types of land use.The comprehensive index of land use in the study area showed an upward trend in the past 10 years,and the intensity of land development and utilization increased,but the land utilization rate rose gently on the whole.From 2010 to 2019,the the eco-environment in the study area gradually degraded,mainly due to the decrease of forest land and cultivated land.The conclusions of this study provides reference for planning and sustainable development of land use in urban areas in small river basins in southwest China.
