木本能源植物文冠果在我国的分布规律研究

为了给木本能源植物文冠果的综合利用提供科学依据,对其在我国的分布规律进行了调查研究,结果表明:文冠果在我国的分布范围为28°34~47°20′N7、3°20′~120°25′E,遍布华北、华东及西北地区。沟壑纵横的黄土高原是文冠果分布最为集中的地区。分布区主要在暖温带气候区内,天然分布区内植被以灌草为主。土壤以黄绵土占绝对优势,其次是黑垆土、风沙土、山地褐土、栗钙土等。文冠果呈小面积块状零星分布,水平分布不连续,垂直分布上下限随着经纬度的增加有降低趋势。辽宁建平-北京-山东青岛-安徽合肥-河南栾川-陕西洛南-甘肃平凉-青海循化-西藏察隅一线以西以北地区均有文冠果分布,而在此界以东以南地区无文冠果分布。

Regular Distribution of Woody Energy Plant Xanthoceras SorbifoLia Bunge.in China

In order to provide the scientific basis for the synthetical utilization of Xanthoceras sorbifoLia Bunge.,its distribution orderliness in China was investigated.The result was that:the geographic distribution of Xanthoceras sorbifolia Bunge in China spans from 28°34′N to 47°20′N in latitude and from 73°20′E to 120°25′E in longitude.The ravines and gullies criass-cross loess plateau was its centralized distribution region.It can grow in temperate region and was found in North China,East China and Northwest of China,including 14 provinces(municipalities and autonomous regions).In the natural distribution regions,the vegetation was mainly made up of grasses and shrubs,and the soil types were loessal soil(the others were black mature soil,sand blown soil,brown earth and chestnut soil).The horizontal distribution of Xanthoceras sorbifolia Bunge.was scattered and discontinuous,and the distribution boundary line was the line Jianping of Liaoning Province-Beijing munociplities-Qingdao of Shandong Province-Hefei of Anhui Province-Luanchuan of Henan Province-Luonan of Shaanxi Province-Pingliang of Gansu Province-Xunhua of Qinghai Province-Zayu of Tibet.The resource of the Xanthoceras sorbifolia Bunge.in China was almost found in the west and the north of the line,while few was found in the east and the south of the line.
