摘要:

基于浙江省海宁市2010年Landsat-5 TM 及2016年Landsat-8 OLI两期影像,提取归一化植被指数(NDVI)值,运用线性像元二分模型计算出两期植被覆盖度并分级,进而获取各级植被覆盖度转移矩阵。结果表明:海宁市开展的平原绿化工程期间(2010—2016年),全市平均植被覆盖度增加,且植被类型是主要是从中、低覆盖度植被向高、极高覆盖度植被转移。通过海宁市两期植被覆盖度情况的量化计算与分析,可为科学评价平原地区绿化造林工程成效提供参考。

Abstract:

In order to monitoring the dynamic changes of vegetation coverage in Haining,Landsat-5 TM and Landsat-8 OLI images from the years of 2010 and 2016 were used as information source.The results show that from 2010 to 2016 the plain afforestation in Haining was highly effective.The vegetation types have increased and coverage vegetation.has shifted from a low and medium level to a high and very high level.Through the quantitative calculation and analysis of the coverage vegetation in the two phases of vegetation coverage in Haining,this paper can provide references for evaluating the effects of the afforestation in the plain areas scientifically.

Key words: vegetation coverage, plain afforestation, Haining, dynamic change analysis
