我国地黄人工种植生态适宜性区划研究

Study on Ecology Suitability Regionalization of Rehmanniag lutinosa Libosch. Planting in China

目的进行地黄的生态适宜性区划,为地黄人工种植基地选取和优质工业原料收购区域的确定提供依据。方法以全国740个气象站点、1971-2001年的气象数据为基础,采用"模板模式",应用相似度分析、德尔菲法和空间分析方法进行地黄种植气候适宜性等级划分;以气候适宜性等级划分结果和中国土壤图栅格数据为基础,应用ArcGIS软件进行空间叠加和空间计算,进行地黄的生态适宜性区划。结果地黄最适宜区主要集中在河南北部,以及与河南北部接壤的山西、河北南部,山东西南部和安徽北部地区。新疆以及甘肃的部分地区也有适宜地黄栽培的气候条件。结论应用空间分析技术,从气候和土壤两个方面,进行地黄的生态适宜性区划研究,可以为地黄人工种植基地选取和优质工业原料收购区域的确定提供依据。

Objective To study ecology suitability regionalization of Rehmanniag lutinosa Libosch. for selecting artificial planting base and high-quality industrial raw material purchase of Rehmanniag lutinosa Libosch. in China. Method Based on the meteorological data from 1971 to 2001 of 740 weather stations of China, using similarity analysis, Delphi method and the spatial analysis method to rank regionalization of climate suitability. Based on the climate suitability regionalization and grid data map of China＇s soil, using space overlying and calculating method of ArcGIS software to regionalize ecology suitability of Rehmanniag lutinosa Libosch. planting. Result The most suitability area of Rehmanniag lutinosa Libosch. planting are north of Henan, Anhui and Shanxi province, south of Shandong and Hebei province. There are some climate suitability areas in the Xinjiang and Gansu province. Conclusion Using the spatial analysis method, based on the climate and soil condition, the ecology suitability regionalization of Rehmanniag lutinosa Libosch. can provide reference for selection of artificial planting base and high-quality industrial raw material purchase.
