苏浙皖珍稀濒危植物保护规划的研究

本文在进行全面野外调查和资料收集的基础上,研究了三省珍稀濒危植物的保护规划。根据人为保护现状和植物的分布及多度等,将该地区65种国家保护植物分为几组,并提出几种类型的保护规划。在就地保护方面,提出增建6个自然保护区、2个国家公园和40多个自然保护点;在迁地保存方面,提出建立一个由地区迁地保存中心、三个省级保存繁殖基地和若干小型引种园圃组成的多层次迁地保存网。本文还提出“就地-迁地”保存规划,这是一种结合了就地和迁地保存优点的规划方法。此外,本文还特别强调了“归化自然”的规划,“归化自然”要求将人工繁育的珍稀濒危植物种群归化到它们原先的生境中去。

A STUDY OF THE CONSERVATION PLANNING FOR THE RARE AND RISK PLANT SPECIES IN JIANGSU,ZHEJIANG AND ANHUI PROVINCES

Based on full field survey and data collection, the conservation planning for the rare and risk plant species in the three provinces is studied. The 65 plant species in the area protected by the state are divided into several groups according to artificial conservation status and plant distributions and aboundances, and several types of the conservation planning are put forward. On the on-ther-spot conservation side, the establishments of six nature reserves, two national parks and more than 40 protection spots are proposed. On the off-the-spot conservation side, it is suggested to set up a multiply off-the-spot conservation network that consists of a regional off-the-spot center, three provincial-level conservation and breeding bases and a lot of small plant transplantation gardens. Furthermore, an "on-the-spot and off-the spot" conservation planning is proposed, which combines the advantages of the two kinds of conservation. In addition, a "naturalizatoin" planning is particularly emphasized, which requires that the artificial breeded populations of the rare and risk plants should be naturalided to their original habitats.
