辽宁省不同土地利用类型的蒸散发特征
Characteristics of evapotranspiration for different types of land use in Liaoning Province
摘要
Abstract
Based on Landsat TM remote sensing images of Liaoning Province in 2014, the characteristics of evapotranspiration for different land use types from the perspectives of time and space were analyzed by calculating the actual evapotranspiration for different land use types and using the discretization function of the ArcGIS software. The results show that the actual evapotranspiration was significantly affected by the land use types, and the intra-annual variation characteristics of actual evapotranspiration varied for different land use types. The contribution of the evapotranspiration depends on the size of the land with a certain land-use type. There is a high degree of consistency between the spatial distribution of evapotranspiration and land use types, indicating that evapotranspiration is closely linked to land use types.关键词
