GIS支持下的鲁东南丘陵区茶树土地适宜性评价
Land Suitability Evaluation of Tea Plant in Rizhao Southeast Shandong Province Based on GIS
【摘要】 首先研究了暖温带茶树品种生长与自然条件的关系,分析确定了典型区日照市茶树种植的评价因子;然后在1∶5万比例尺地图上,运用ARCGIS对一月平均风速和不同高度下温度因子进行了模拟,并在模拟了天文辐射的基础上对气温因子进行精细订正;同时结合土壤、坡度、相对湿度等因子建立了评价因子量化分级表;最后,运用了模糊数学(Fuzzy)综合评价模型,实现了土地适宜性评价。按照评价结果将研究区分为茶树最适宜、适宜、次适宜和不适宜种植区,并对各类区进一步作了分析和讨论。
【Abstract】 Based on the analyzing of the relationship between tea plant growing and natural condition, the paper chose land suitability evaluation indexes of tea plant in Rizhao city Shandong province. On the background of map at scale 1∶50 000. The average January wind speed and temperature factors were spatially interpolated using GIS and DEM, and the temperature factors were corrected accurately with the extraterrestrial solar radiation which was simulation on DEM. The evaluation factors system was build with the average January wind speed, temperature factors, relative humidity, slope, soil texture and soil pH. At last, the comprehension evaluation was achieved by the way of combining the fuzzy model and GIS.the evaluation result was divided into four grades and was analyzed for every one.
