Abstract: Under a new developmental idea,i.e.,sustainable development,the modern societal and economic development is moving step by step towards the orbit of harmonious development with eco environment.In this course,the research on eco environment carrying capacity is very impor tant.In order to quantificationally analyze eco environment carrying capacity,this paper developed a quantitative method under the guidance of sustainable development principle.The main content includes 3 parts:(1) to quantify the development quality of society,economy and eco environment al subsystem and establish the index system and Pattern Recognition Approach(PRA);(2) to iden tify the Sustainable Development Degree (SDD) and to quantify the development quality of the study area with it; and (3) to build eco environment carrying capacity analysis model.Under the prerequisite of maintaining a certain eco environmental quality,using the model to adjust population quantity and economic scale and make the "society economy eco environment" system have higher development quality.The corresponding population quantity and economic scale are the indicators of eco environment carrying capacity.In the case study,this model was applied to the Haihe Basin.Taking 1998 as the year of the Haihe Basin present situation, considering the south to north water transfer project,the eco environment rehabilitation project and the improvement of water use efficiency,6 kinds of scenario schemes were designed.Based on the above method,quantification analysis of the changes of eco environment carrying capacity was made.Research result shows to improve water supply ability through the south to north water transfer project and to improve water use efficiency by changing industrial structure constitute one of the basic ways to solve the water eco environmental crisis in the Haihe Basin.The present research will offer scientific basis at both national and local levels for the formulation of sustainable development policies and the determination of regional population and economic development scale that is suitable to local natural resource and environment situations.

Key words: eco environment, carrying capacity, water resource, Haihe Basin
