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。 -
In order to solve this problem, we find a kind of herbages plant - sabaigrass ( eulaliopsis binata ) which not only can accommodate the badly environment of purple soil but also have excellent water and soil conservation effect and good economic benefit. this study adopt quantitative and qualitative methods, through comparative study of four different utilization types : sabaigrass treatment, grass tree solid plating treatment ( planting sabaigrass under fruit trees treatment ), bare land treatment, natural wild grassland treatment, study water and soil conservation effect, soil water condition, soil constructors condition, soil fertility condition and soil surface temperature, then evaluated the water and soil conservation effect of plating sabaigrass in purple soil bare sloping field and probed into water and soil conservation mechanism. the main results are as follows : 1

2. the structure of purple soil is meliorated by sabaigrass. when contrast to bare land treatment and natural wild grassland treatment we knew that sabaigrass treatment and grass tree solid plating treatment reduced soil bulk density, enhanced soil capillary porosity, non - capillary porosity and porosity ratio, decreased soil sand grain content, enhanced soil clay grain and silt grain content so as to reduced the dispersal degree of soil, improved the aggregate capacity of soil, increased the amount of soil aggregate structure, meliorated the water permeability of soil, accelerated the form of good soil structure
