黑河中游景观格局变化特征及其与水文过程相互关系分析 ——以张掖地区为例
Relationship between landscape pattern and hydrologic processes in midstream area of the Heihe River basin
摘要
Abstract
The ecosystem in Zhangye Region,middle stream of the Heihe River basin located in northwest of China,is faced with great menace as a result of great temporal and spatial changes in hydrological processes as well as the water resource shortage problems restricting sustainable development of society and economics in northwest arid area of China.Relationship between landscape pattern and hydrological processes is analyzed based on LUCC data in 1986,2000,2005,2007,and 2011,hydrological data at Yingluoxia and Zhengyixia hydrological stations, and precipitation data at Zhangye meteorological station. Basic characteristics and relationship between landscape pattern and precipitation or runoff have been obtained. Fragmentation of artificial landscape was found to have increased,area of woodland decreased,and inflow from upstream increased.However, outflow to downstream has decreased. Inflow has shown great effect on artificial landscape,precipitation had great effect on natural landscape.This work will provide important technical support for protection of ecosystem,land and water resources management in the study area.关键词
