Evaluation for Ecological Trail and Suitable Distribution Area of Epimedium koreanum Nakai in Jilin Province Based on GIS Technology
摘要
Abstract
Objective:To study the general distribution rules and the main influence factors of Epimedium koreanum Nakai in Jilin Province,and establish the ecological suitability distribution.Methods:A field survey was carried out to record the longitude and latitude of E.koreanum Nakai in the main distribution areas in Jilin Province.The ecological data of the distribution areas were obtained using GIS technology and a variety of ecological types of spatial data.Mathematical statistics method was used to analyze the ecological data,and clarified the ecological factors which were significant influence on the distribution.Results:Five of the twenty eight ecological data,include altitude,the wet monthly precipitation,the dry monthly precipitation,coefficient of variation of seasonal precipitation and soil pH degree were significant impact the distribution of E.koreanum in Jilin Province.The suitable distribution area of E.koreanum were mainly distributed in the mountainous and semi-mountainous areas of southern Jilin Province,the total area was about 27 256 km2.Other major ecological factors such as topography,climate,soil,vegetation were also refined.Conclusion:GIS technology can directly extract multi-types ecological data of distribution areas,and study the influence of ecological factors on the distribution of plants and formulate the plant suitable distribution area.The above research showed that use GIS technology to carry out the ecological research of wild herbs,and provides a new idea for the further development of the ecological research of wild herbs.关键词
