水库区域土地利用时空变化分析.

The construction and operation of reservoir project will have an important impact on regional land use and ecosystem stability. The analysis of spatial and temporal dynamic changes of land use in reservoir area can provide technical support for the protection of land resources and ecological environment in reservoir area. Taking the first tributary of the upper reaches of the reservoir in the upper reaches of the reservoir area above the dam to 92 m of the Chushandian Reservoir as an example, by interpreting, calculating and analyzing satellite remote sensing images from different periods of the reservoir area, the land use transfer matrix could he generated, and a single type dynamic degree and comprehensive type dynamic degree model could be constructed to qualitatively analyze the spatial and temporal characteristics of land use in the reservoir area. The results show that from 2000 to 2018, the land use structure of Chushandian Reservoir has been changed significantly, and the spatial dynamic degree of different land use types in different periods is obviously different, hut the spatial pattern has been changed little. Reservoir construction will play a leading role in regional economic and social development. Land use structure should he adjusted in time to strengthen the protection of land resources and ecological environment in reservoir area. [ABSTRACT FROM AUTHOR]
