Valley economy is a new angle of view in the research of mountain development,the date of important valley in Miyun county were base on research.In this paper,aimed at land supporting capacity of economic development,grain production and ecological protection in valley,we built the quantitative evaluation method of land support capacity and evaluated it,and then compared support capacity and actual demands to find out response approach from development experience in valleys when the land support capacity is not enough.The results show that land support capacity in space was obvious non-balanced,the value difference is bigger in valleys.On the whole the land support capacity is insufficient,but through development of valley economy and optimization of response approach,but there was a balancing trend between land support capacity and development demands,that is,land support capacity was gradually improved and strengthened.
