Abstract
Landscape pattern and eco-hydrological process had changed greatly after seven times emergency water transportation in the lower reaches of Tarim River, Xinjiang, China. After analyzing the changes of eco-hydrological process, ground water level, soil moisture and vegetation growth etc. of emergency water transportation, remote sensing images in 2000 and 2005 year which present the situation before and after the emergency water transportation were processed and dynamic change characteristics of landscape pattern were analyzed. The changes of landscape pattern were described as follows: The forest land, waters, farmland and construction landscape area increase, and forest land increases the biggest, which increased by 23.03% during last 5 years. Waters landscape change is only inferior to forest land, which increased by 16.04%. The lawn, sand and Gobi saline-alkali land landscape area reduced; lawn and farmland had made the biggest contribution to the increase of forest land by 6.46% and 4.79% in the year 2005. Landscape diversity index, evenness index, fractal dimension and general fragmentation increased, but dominance index reduced. The results indicate that RS plays the vital role in the macroscopic dynamic change analysis of landscape pattern and seven times emergency water transportation has greatly influenced eco-hydrology process and landscape pattern changes in the lower reaches of Tarim River.
