| 摘 要： | 为研究我国典型农牧交错区长时序地表生态变化特征,以内蒙古自治区陈巴尔虎旗为例,基于2000—2016年MODIS NDVI数据,综合应用MVC、像元二分模型、一元线性回归模型、T检验等方法,对陈巴尔虎旗植被覆盖时空变化特征进行定性定量分析。结果表明：受气候、地形、人为因素等影响,陈巴尔虎旗地区植被覆盖度呈现东高西低的空间分布特征;17年该地区的植被覆盖整体呈波动下降趋势,平均植被覆盖度由2000年的58.81%减少到2016年的48.14%;植被覆盖度减少的区域占55.66%,主要分布在宝日锡勒镇、巴彦库仁镇、鄂温克民族苏木。研究成果为定量评估区域生态变化的累积效应提供了数据支撑。

| Abstract: | To investigate the temporal-spatial variation characteristics of typical farming-pastoral transitional zones in China, Chen Barag Banner, Inner Mongolia was taking as study area.Based on the MODIS NDVI remoting sensing images from 2000 to 2016, the temporal-spatial characteristics of vegetation coverage in Chen Barag Banner area were quantified and quantitatively analyzed by using MVC, pixel decomposition model, linear regression model, T test and other methods.The results showed that the vegetation coverage in the study area was influenced by effectors including climate, topography and human.The spatial distribution characteristics of high to low from the east to west were discovered.The overall vegetation coverage displayed a fluctuant decrease over the past 17 years, and the average vegetation coverage was decreased from 58.81% in 2000 to 48.14% in 2016.The area of vegetation coverage was reduced by 55.66%, which was mainly in the areas of Baorixiletown, Bayankurentown and Evenk Ethnic Sumu.This study would provide data support for quantitative assessment of the cumulative effects on regional ecological change. |
