Evolution trend of KRD based on high-resolution remote sensing images: An example of the east mountain, Mengzi ecological management region
摘要
Abstract
The purpose of this work is attempt to quickly and accurately determine the karst rock desertification (KRD) evolution trend with high-precision in small areas and provide scientific evidence and basic data for quantitative evaluation and precise treatment of KRD. We select the typical area of KRD-ecology management area in the east mountain of Mengzi as the study area. Based on SPOT5 data acquired in November 2006 and Pleiades data in January 2015, we use a method combining NDVI and FVC of the ecological management region to collect KRD information form remote sensing data. Statistical analysis on the data of 2006 to 2015 shows that the KRD were very serious, high KRD accounting 73.55％, moderate KRD 5.36％, and slight KRD 0.53％, respectively, while none-KRD only 14.86, with the shadow and water area accounting for 5.71％ of the total. From the year 2006 to 2015, the area of high KRD increased slightly, from 72.37％ to 73.55％, and the area of moderate KRD reduced from 11.58％ to 5.36％. Although the area of mild KRD was small, it represented the significant reduction, from 4.35％ to 0.53％, nearly disappeared. The area of non-KRD increased substantially, from 6.06％ to 14.86％, so on the whole the occurrence of KRD tended to decline.关键词
