Abstract:

为了探索岩溶峰丛区生态参数与石灰岩基岩表面溶蚀率的相关性,用相关生态参数反演土层下石灰岩基岩表面的溶蚀率,从而间接估算其变形。选择桂林丫吉村岩溶峰丛区为研究区,以Landsat5TM多光谱数据为信息源,提取归一化差值植被指数(normalizeddifferencevegetationindex,NDVI)、地面温度及土壤湿度等遥感参数;运用SPSS统计软件对这3种参数分别与石灰岩溶蚀率进行了相关分析,确定其相关系数分别为-0.91,0.85及0.93;在此基础上,通过逐步回归分析,建立了运用NDVI估算植被覆盖下石灰岩表面溶蚀率的遥感反演模型。结果表明:NDVI与石灰岩溶蚀率相关性最大,所以植被信息是石灰岩表层基岩溶蚀的主要间接标志;溶蚀率与NDVI指数存在线性关系,因此只要已知研究区其他地区的NDVI指数,即可估算出该地区的石灰岩基岩表面溶蚀率。
