Abstract

Abstract: This paper intended to find out the characteristics of the vegetation cover changes in the grassland of Ili Valley,where the grassland is the main component of the ecosystem. Based on MODIS NDVI time series data during 2000-2016 and the methods of Mann-Kendall test,Theil-Sen Median trend analysis and R/S analysis,the changing trend of grassland NDVI in Ili Valley during the last 17 years was analyzed. The results showed:During 2000-2016,the NDVI of the grassland in Ili Valley showed a significant decline trend in total,and NDVI of 88.07% area decreasing,of which 49.62% reached significant level. Among all the grassland types in Ili Valley,the mountain meadow has the largest area,the highest averaged NDVI value,and the highest averaged rate of NDVI reduction. The NDVI of its 95.76% area decreased,and 73.10% reached significant level. The NDVI changing trend of the 97.77% grassland in Ili Valley showed positive persistence,indicating that NDVI of the grassland would continue to decline for a certain period of time in the future in most part of Ili Valley. Compared to temperature,the inter-annual variation of precipitation was more closely correlated to the change of NDVI of grassland in Ili Valley.

Key words: Change in Grassland Cover, MODIS NDVI, Trend test, Hurst Index, Ili Valley

摘要： 草地是伊犁河谷生态系统的主要组成，为探明其植被覆盖的变化特征，选用2000-2016年MODIS NDVI时间序列数据，应用Mann-Kendall检验、Theil-Sen Median趋势分析及R/S分析，对伊犁河谷近17年草地NDVI变化趋势进行分析。结果表明：2000-2016年伊犁河谷草地NDVI总体呈显著下降趋势，空间上88.07%草地NDVI出现下降，其中49.62%达到显著水平；各草地类型中，山地草甸NDVI平均值最高，面积最广，NDVI平均降低速率最高，其95.76%面积的NDVI出现下降，且73.10%达到显著水平；伊犁河谷97.77%草地NDVI变化趋势呈现正持续性，未来一定时期内绝大部分草地的NDVI仍将继续下降；与气温相比，伊犁河谷降水的年际变化与草地NDVI年变化的相关性更高。
