农牧交错带研究中的现代生态学前沿问题

在回顾了我国农牧交错带的定义、起源、历史变迁及生态景观的独特性及在农业上的重要地位后,初步总结了在此带内几十年来的治理和研究的经验教训。其主要问题是支撑性基础研究不足以及缺乏跨学科的综合与合成。针对国际上现代生态学的动向和研究前沿,提出了加强农牧交错带基础性研究的4 个领域,并对新的研究方法进行了刍议。

FRONTIER ISSUE OF MODERN ECOLOGY IN THE STUDY OF ECOTONE BETWEEN AGRICULTURE AND ANIMAL HUSBANDRY

This paper examines the definition,origin,and historical evolution of the transitional area between farming and pasturing in northern China as well as unique features of the eco landscapes and their essential role to agricultrue,and gives a preliminary summary of the experience and lessons in the management and research of the ecotone in the past decades.The major issue identified is the inadequate research on supporting oriented basic study and lacking of integration and synthesization of cross disciplines.In light with trends and frontier studies of modern ecology in international communities,four fields concerning intensification of basic studies of the transitional area between farming and pasturing are raised and a tentative suggestion on new research methodology is put forward.
