They are jinfo mountain in nanchuan county ( natural protection section ), wuling mountain in qianjiang county ( national emphases forest demonstration county which forest cover rate is beyond 50 % ) and zhongliang mountain in beibei county ( artificial destruction is very grave ). some main land use patterns i. e. woodland, garden, infield, abandon infield, shrub and grassplot are selected in those three sample sites. four aspects on soil fertility index of karst environment under different land use patterns in these three sample sites, are revealed in this paper, by using the field test, indoor measure and analysis, outdoor experiment and field investigation, and the knowledge and technique of soil, ecology, physics and chemistry etc. they are physical characteristic ( effective soil thickness, organic layer thickness, soil texture, water - stable aggregate and soil water etc. ), chemical fertility ( organism, omni - n, omni - p, omni - k, alkali - nitrogen, available p, available k and rapid available k etc. ), soil animalcule ( bacteria, fungi, actinomyces and their grosses ) and soil - seed - pool ( plant community diversity index ) in karst ecosystem
本研究以重慶市的南川金佛山（自然保護區） 、黔江武陵山（國家重點退耕還林示範縣，森林覆蓋率50以上）和北碚中梁山（遭人為破壞嚴重）典型巖溶區為對象，選擇了幾種重要的利用方式，包括林地、果園、耕地、棄耕地和灌草坡，採用野外巖溶生態調查和室內試驗測量分析相結合的方法，以不同土地利用方式巖溶土壤肥力為重點，對不同土地利用方式土壤肥力特徵進行量化分析，找出巖溶土壤肥力差異的主要方面及其根本原因，論文主要從土壤剖面物理退化指標（有效土層厚度、有機質層厚度、質地、團聚體、水分含量等） ，化學肥力退化指標（有機質、全n 、全p 、全k 、堿解n 、速效p和速效k等） ，樣地土壤微生物指標（細菌、真菌、放線菌數量及總量）以及樣地土壤種子庫植物群落多樣性等4個方面對重慶典型巖溶區的土壤肥力特徵進行了較為詳細的分析研究，為巖溶地區士壤資源的合理利用及結構的調控管理提供依據。 -

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。 -
