Abstract:
The research on distribution and quality suitability division of Desmodium styracifolium were formulated by Maxent and ArcGIS model based on the content of schaftoside and polysaccharide of D. styracifolium and its field research in the south and southwest areas of China (Guangdong, Guangxi, Hainan and Yunnan), and the most suitable habitats of distribution suitability and quality suitability were screened. The distribution suitability results indicated that average air temperature in April,mean temperature of coldest quarter, soil type, coldness index were found as the four dominant factors contributing to the plant distribution. The quality suitability results indicated that: ①Polysaccharide content and precipitation in April show significant positive correlation;Schaftoside content and mean temperature of April, mean temperature of coldest quarter show significant negative correlation. Schaftoside content shows significant negative correlation with the precipitation in October and November and the sunshine duration in April and May, while there is a significant positive correlation between schaftoside content and precipitation in April and temperature seasonality standard deviation, and a highly significant positive correlation was found between schaftoside content and precipitation in February and March. ②The quality zoning map was drawn depend on general content of polysaccharide and schaftoside as the index of quality. And this research provides scientific location basis for the production regionalization, cultivation bases selection and directive breeding of D. styracifolium.
