农牧交错区苜蓿草业产业化开发研究

我国北方农牧交错区不仅是生态环境人为破坏最为严重的地区，也是土地荒漠化发展速度最快的地区。根据农牧交错区面临的主要生态问题，选择退耕还草、发展苜蓿草业，对该区生态、经济、社会的可持续发展具有重要作用。该文结合农牧交错区的实际，提出了该区苜蓿草业产业化开发的基本模式、阶段特征及基本对策。

STUDIES ON THE DEVELOPMENT OF CLOVER INDUSTRY AT MIXED AREAS OF AGRICULTURE WITH ANIMAL HUSBANDRY

Northern China where agriculture is mixed with animal husbandry is an area suffered most severely from human damage for its ecological environment. It is also an area that land hungriness develops with high speed. According to the major ecological problems confronting the areas mixed agriculture with animal husbandry, it is of important function for sustainable ecological, economic and social development to quit planting, to grow grass, and to develop clover industry. This practice raises a basic mode for developing clover industry in areas where agriculture is mixed with animal husbandry; indicates the stage traits for clover industry development; and also puts forward some basic countermeasures for this development.
