基于MODIS的贵州省黎平县植被变化
MODIS-Based vegetation change in Liping County of Guizhou
摘要
Abstract
Based on the MODIS-NDVI data and temperature and precipitation data during the past 2000-2014 years, the vege-tation cover change and its influencing factors in Liping county were analyzed .Results showed that: 1) from the change of space , the vegetation degradation area of Liping county only accounts for 14% of the study area in the past 15 years, the improvement area ac-counts for 75%, and the no change area is about 11%.The degraded areas are mainly distributed in the northeast and central re-gions.2) The annual NDVI value increases with the elevation .The maximum annual NDVI value appears in the region above 1200 m and the minimum annual NDVI area is below 200 m.During the study period , the average annual NDVI value was negatively correla-ted with annual precipitation and annual mean temperature , and the effect of temperature was significant .关键词
