AGRICULTURAL CLIMATIC REGIONALIZATION FOR LONGAN CULTIVATION IN GUANGDONG PROVINCE
摘要
Abstract
In the context of global warming, the use of GIS and computer technology in agricultural climatic regionalization for longan cultivation can benefit and serve the longan planning. According to the climate data from 1971 to 2000 of Guangdong Province and the climatic conditions of longan growth, the authors analyzed and identified indexes for climatic division, which contain annual average temperature, extreme minimum temperature, sunshine hours from mid-April to early May and the accumulated temperature which is greater than or equal to 10 C during a period of 30 years. Then an overall index of climatic division was obtained on the basis of the equal-weight principle. On the basis of the correlation coefficient among the four division factors and geographical factors, the gradient inverse distance method was used to get raster distribution maps for each meteorological element with a grid resolution of 1 km2. By the function of spatial analysis of GIS, longan cultivation zoning maps of Guangdong Province were completed. The most suitable region accounts for 25.6％, the suitable region accounts for 26.3％ and the sub-suitable region accounts for 27.1％. Finally, the zoning maps can be used by departments of agriculture planting and planning and the government in choosing zones of crop growth.关键词
