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。

  13. The vegetation type was classified in the east transect by unsupervised classification using the data ( ikmx 1km ) from noaa meteorology satellite from 1995 - 1996, and the article analyzed the change of ndvi of all kinds of vegetation types, in the same time analyzed the forest dynamics in typical ecotone ( warm temperate zone to semitropical in qinling woods ) using the higher spatial resolution tm data

    本論文利用1995 - 1996年noaa氣象衛星的ndvi （ 1km 1km ）數據，採用無監督分類方法對中國東部樣帶南方部分進行植被類型的劃分，分析各植被類型的ndvi變化情況；並利用較高精度的tm數據分析典型交錯區域（暖溫帶到亞熱帶的秦嶺林區）的森林動態變化情況。

  15. The radical reason of lower ecosystem productivity and disharmonic developing in this ecotone is the improper configuration inner animal husbandry for example of ansai county and big animal scale exceeding the threshold of the primary productivity for example of wuchuan county, which above - mentioned leads to the fact that coupling mechanism between agriculture and animal husbandry system has not been established, and agriculture and animal husbandry is still in the state of disharmonic on the whole. 3

    主要表現為兩種典型結構模式，一種以安塞縣為代表，農牧能值總體利用率較高，但畜牧業內部結構偏重食糧動物使得高質能轉化率低下；另一種以武川縣為代表，農牧業結構總體上朝趨于協調方向發展，但畜牧業規模過大，由於草畜平衡嚴重失調，導致農牧系統耦合機制難以穩定。
