摘要
为了给极小野生植物种群绒毛皂荚恢复发展提供科学依据,本文从知网等专业学术网站和微软必应搜索引擎进行搜索,共收集文献108篇,分析了种群的社会认知和扩展,结果如下:(1)认知上存在学界初步接纳新物种但缺乏非专业界认知、学界深化认知与非专业界开始关注、业内和非业内学界认知停滞不前以及业内和非业内学界对其认知进一步深化4个时段。(2)野生种群数量从1954年发现5株起,先后在2009、2012、2019、2021、2022和2023年六次调查发现10株,但又先后消亡5株,现有野生植株10株(有3结果株1雄株)。(3)种群扩展大致可分为原地和异地初始扩展、第一子代种子回归原产地并开始向域外发展、扩大本地种群数量和外输扩大分布区的发展、野生种源和优树种源同时向外域扩展四个阶段。(4)根据分析结果,提出了继续发展的建议。
In order to provide a scientific basis for the restoration and development of the extremely small wild plant population of Gleditsi a jap onic a var.velutina,108 literatures were collected from professional academic websites such as CKNI and Microsoft Bing search engine,and the social cognition and expansion of the population were analyzed.The results are as follows:(1)Cognitively,there were four periods including the academic circles initially accepted new species but lack of non-professional cognition,the academic circles deepened cognition and the non-professional academic circles began to pay attention,the academic and non-professional academic circles cognition stagnated,and the academic and non-professional academic circles further deepened their cognition.(2)The number of wild population since the discovery of five plants in 1954,ten plants have been found six times in 2009,2012,2019,2021,2022,and 2023,five of which have died out.There are ten wild plants(three bearing plants and one male plant)currently.(3)The population expansion could be roughly divided into four stages:the initial expansion in original and in different places,the first generation of seeds returning to the origin and starting to devvlop outside the region,the development of expanding the number of local populations and expanding the distribution area of export,and the simultaneous expansion of wild provenances and superior tree provenances to the outer region.(4)According to the analysis results,suggestions for further development were put forward.
