基于MNDWI的丹江口水库面积提取及其动态变化监测
Water Area Extraction and Dynamic Monitoring of the Danjiangkou Reservoir using MNDWI
摘要
Abstract
Danjiangkou Reservoir because of its good water quality, relatively stable carrying capacity, and on the ground to artesian water to some unique advantages such as the northern area was selected as the water source of south-to-north water transfer project� This article selects 2002-2015 period of 42 Landsat TM/ETM + remote sensing image, using the fixed type normalized difference index ( MNDWI) extract 14a changes in the area of the reservoir water dynamic information� The results show that the September 2005 after the Danjiangkou Reservoir dam heightening reservoir area began to increase; The four seasons of Danjiangkou Reservoir area of study, large variations in the area of Danjiangkou Reservoir water, autumn winter variations in the area of reservoir water area is lesser, variations in the size of the spring and summer is relatively stable;Altogether ( Sep to Dec) in the reservoir area of the change of the amplitude is larger, the mutagenicity in April ( Jan -Apr) and level period ( May to Aug) , small variations in the reservoir area of the plentiful reservoir area on the whole is greater than the mutagenicity and level period reservoir water area� Strengthen the Danjiangkou Reservoir water.关键词
