荒漠有毒灌草资源的培育及综合利用——防治荒漠化的新思路

CULTIVATING AND COMPREHENSIVE UTILIZATION OF POISIONOUS SHRAB AND HERB RESOURCES ON DESERTIFIED LAND ——A NEW IDEA OF CONTROLLING DESERTIFICATION

介绍了我国荒漠有毒灌草的资源状况，其生物学、生态学和固沙机制及综合开发利用的成果，提出了培育和综合利用荒漠有毒灌草资源防治荒漠化，应用新技术对有毒灌草中毒性成分进行研究及开发利用，使综合利用有毒灌草工程成为具高附加值的新沙产业，且使荒漠化的治理与发展当地经济可能形成相互促进、持续发展的良性循环。并就该途径在荒漠化治理及发展我国荒漠化地区经济等方面的意义及其前景进行了探讨。

It is proposed for the first time a new idea of controlling desertification with cultivating and comprehensive utilization of resources of poisonous shrabs and herbs on desertified land. In the past, in both textbooks and practices of controlling desertification the poisonous shrabs and herbs were not chosen to be planted on the desertified land, moreover they were studied to be removed from the desertified land, because they could not be used directly for their toxicity. It is introduced the resources of poisonous shrabs and herbs on desertified land in China; their biology, ecology and sand_fixation mechanism and achievement of their comprehensive utilization and development. Research on the toxic compounds in the poisionous shrabs and herbs on desertified land and their comprehensive utilization and development have made the project of the poisionous shrabs and herbs a new and high beneficial industry on sandy desertified land. It has made desertification rehabilitation and development of local economy possible to form a good co_promotive relationship. This paper discusses significance and prospect of the new idea of controlling desertification and developing the economy in desertification area in China and the world.
