基于MODIS—NDVI的梅江流域耕地复种指数提取研究
A Methodology for Multiple Cropping Index Extraction of MeiJiang Basin Based on MODIS/NDVI
摘要
Abstract
According to the situation that the existing non-point pollution models exist a certain limi- tation when simulating in scattered planting, intensive cultivation and multiple cropping's cultivated land ,the paper carry out the multiple cropping index extraction research based on remote sensing that can reflect the cultivated land'characteristics to provide the basis data for non-point pollution. This paper chose MeiJiang basin as the study area,with the MOD13QI NDVI data as data source, used the HANTS method to reconstruct the time series NDVI data, designed twi-differential algorithm to build multiple cropping index model in the GIS spatial analysis module, and combined with 2010 MeiJiang Basin's cultivated land-use status data to extract 2010 and 2011 's MeiJiang basin multiple cropping index. Validated by sampling data, the accuracy of multiple cropping index is 83.3 %, hay-ing high precision,which can satisfy the improvement need of existing non-point pollution model.关键词
