黄土高原经济植物资源的保护性开发对策

针对黄土高原经济植物资源的开发利用现状及历史,分析了黄土高原经济植物资源的保护性开发原则。(1)继续实施植被建设工程,促进生态环境的改善与重建;(2)在政府统一管理下,适度开发野生资源,建立经济植物生产基地;(3)开发植物资源综合利用的高新技术和先进实用技术。实现这一目标的具体对策是:加强珍稀濒危的经济植物的保护生物学研究,并建立各类野生经济植物园;加强经济植物的引种驯化、品种选育工作,建立经济植物良种苗木繁育基地和推广体系;加强经济植物的加工技术研究,建设经济植物的加工业,对次级产品进行市场化、产业化。

Economic Plant Resources and Its Sheltered Utilization in Loess Plateau

After introduced economic plant resources and its utilizated status in the loess plateau, the principles of sheltered utilization on economic plant resources in the region are analyzed. And the countermeasures, which can realize sheltered utilization of economic plant resources, are put forward. To realize sheltered utilization on economic plant resources in the loess plateau, the principles ought to be scrupulously abide by as follows. (1) Eco-environment rehabilitation projects are continuously carried out in order to improve ecological system of the region; (2) Based on scheming management of the government, wild resources of economic plants are limited to be utilized and cultivated base on economic plants are encouraged to upbuild; (3) Key technique and practical techniques are tried hardly to develop about comprehensive utilization of economic plants. The countermeasures are put forward: Enhance the research of conservation biology on rare and endangered economic plants in the loess plateau, and set up botany garden and arboretum about wild economic plants; Enhance the research on economic plants introduction and acclimatization, and construct breeding base and spreading system of excellent varieties of economic plants; Enhance engineering research of phytochemistry on economic plants, and develop economic plant industry in order to realize price increment of secondary products.
