【摘要】：針對穿龍薯蕷資源保護和人工栽培區(qū)選擇的實際問題,通過對吉林省內穿龍薯蕷進行實地調查,運用Max Ent模型和GIS技術,篩選出影響穿龍薯蕷分布的主要環(huán)境因子,并對穿龍薯蕷進行分布區(qū)劃研究,繪制吉林省穿龍薯蕷分布區(qū)劃圖。Max Ent模型研究發(fā)現(xiàn)溫度季節(jié)性變化的標準差、10月份降水量等6項主要環(huán)境因子對穿龍薯蕷的生長適宜度影響最大,生長適宜度數值范圍為4.612 08×10-6~0.544 31,利用分位數法對穿龍薯蕷進行分布區(qū)劃,劃分為高適生區(qū)、中適生區(qū)、低適生區(qū)和不適生區(qū)4部分。其中高適生區(qū)集中在吉林省中部和南部地區(qū),總面積47 988 km2。利用Arc GIS提取采樣點的環(huán)境因子,統(tǒng)計主要環(huán)境因子在各適宜區(qū)內的數值情況。該研究繪制的吉林省穿龍薯蕷分布區(qū)劃與實際情況基本一致,為明確最適合穿龍薯蕷生長的自然環(huán)境,也為開展穿龍薯蕷資源的保護和栽培區(qū)選擇提供參考依據。
[Abstract]:In view of the practical problems of the protection of Dioscorea zingiberensis resources and the selection of artificial cultivation area, the main environmental factors affecting the distribution of Dioscorea zingiberensis were selected by field investigation, Max Ent model and GIS technology. The distribution zoning of Dioscorea zingiberensis was studied. The study on the distribution of Dioscorea zingiberensis in Jilin Province. Max Ent model showed that six main environmental factors, such as temperature seasonal variation standard deviation and precipitation in October, had the greatest influence on the growth suitability of Dioscorea zingiberensis. The range of growth suitability was 4.612 脳 10 ~ (-6) (0.544.31). The distribution of Dioscorea zingiberensis was divided into four parts: high, middle, low and unsuitable by quantile method. The high suitable area is concentrated in the central and southern areas of Jilin Province, with a total area of 47,988 km2. The environmental factors of sampling points were extracted by Arc GIS, and the numerical values of the main environmental factors in each suitable region were analyzed. The distribution regionalization of Dioscorea zingiberensis in Jilin Province is basically consistent with the actual situation, which provides a reference for determining the most suitable natural environment for the growth of Dioscorea zingiberensis, and for developing the protection of Dioscorea zingiberensis resources and the selection of cultivation area.
