Abstract: The establishment of human culture depends on its system and therefore,in the discussion of the impact of human society on the source of water and soil,the balance control of its own will be dealt with first,which is decided by its structural features.The existing human culture in its essence is operated by two sets of laws ---the biological laws and social laws.In the operation of the same culture these two sets of laws can either closely linked or disjointed to a extent.While linked closely it displays its great vitality but in confusion it will show its degradation and produce its strong influence on the eco-system of the nature and the source of water and soil concerned as well,hence causing eco-crisis.The paper lays its stress on the double laws of cultural establishment and the mechanism of mutual controlling balance and how to display the supporting function of cultural stable continuity of the natural eco-system.In addition,counter-measure for the solution of eco-crisis is also put on agenda.

Key words: eco-anthropology, cultural structure, eco-crisis, dual features
