Based on an analysis of the history and present status of the farmland - pastoral ecotone in the northern part of china, a new point of view was proposed in this paper for the construction of eco - environmental systems, namely, the industrial structure has to be modified so as to make a functional integration between different parts of the whole system : to give priority to a combination between cultivated grassland and in - shed feeding of domestic animals, and at the same time, to employ a new model of animal husbandry so that the degradated natural grassland can be recovered ; to develop a new type of processing industry for agricultural and forestal products so as to create a pluralistic enterprise structure ; to make a better use of water resources by taking advantages of the abundant resources of energy and minerals, and to restrain the expansion of industries of high environmental cost ; to employ techniques of integration management and restoration ecology, and to speed up the process of woodland and grassland recovery ; to make a thorough plan for arrangements of hills, waters, roads, farmlands, forests and pastures in order to gain an integration at landscape level
摘要在簡要分析中國北方農牧交錯帶形成歷史和現狀的基礎上，提出了北方地區生態環境建設必須從產業結構調整出發、進行系統功能整合的思路：把人工飼草業舍飼畜牧業擺在農牧交錯帶經濟發展的優先位置，推行新型畜牧業經營管理模式，促進天然草場改良復壯；發展「綠色」農林牧產品精細加工業，建立多元化產業結構；發揮能源和礦產資源優勢，合理利用水資源，限制以破壞環境為代價的產業的發展；推廣區域綜合治理與生態恢復技術，加大退耕還林還草的力度；山、水、路、農、林、牧統一規劃，實現生態系統在景觀水平上的整合。 -
