【摘要】：中国草原生态系统退化是一个亟待解决的问题。采用文献研究和实地调查的方法,阐释中国丰富的植物种质资源,主要如下:中国植物种质资源极其丰富,已收集保存了大量的农作物及其近缘种(其中82%为本土资源)、野生植物种质资源(其中98%为我国的野生资源)。在我国保存的植物种质资源中,饲料植物资源、药用植物资源、水土保持和生态防护植物资源等重要的种质资源,许多是草原生态系统的固有成分。因此,充分利用我国丰富的植物种质资源进行主动干预、修复草原生态系统是值得大力推行的积极手段。提出了利用本土种质资源修复退化草原生态系统的对策,包括开展科学研究、注重多样性、慎用外来物种、体现生物文化多样性。
[Abstract]:Grassland ecosystem degradation in China is an urgent problem to be solved. The abundant plant germplasm resources in China are explained by the methods of literature research and field investigation, mainly as follows: China is extremely rich in plant germplasm resources. A large number of crops and their relative species (82% of which are native resources) and wild plant germplasm resources (98% of which are wild resources of China) have been collected and preserved. Among the plant germplasm resources preserved in China, fodder plant resources, medicinal plant resources, soil and water conservation and ecological protection plant resources are important germplasm resources, many of which are inherent components of grassland ecosystem. Therefore, to make full use of the abundant plant germplasm resources in China to intervene actively and repair the grassland ecosystem is a positive means that should be carried out vigorously. The countermeasures of utilizing native germplasm resources to repair degraded grassland ecosystem were put forward, including carrying out scientific research, paying attention to diversity, using exotic species with caution and embodying biological and cultural diversity.
