Evaluation of Ecological Economy Effect and Land Use Change in the Farming-Pasture Zigzag Zone of Hebei Province

LUO Jian-mei et al (College of Resources,Shijiazhuang University of Economics,Shijiazhuang,Hebei 050031)  
The land use and cover change in the period of 1997-2005 is studied based on the land investigation data.Further more,the article analyzes the effect of land use/cover change on ecosystem service value with ecosystem service assessment methods used by Costanza R.and so on.The results show that the land use and cover has changed enormously in the past eight years,and it has resulted in the gradual enhancement of ecosystem service value.The increased ecosystem service values are 56.6×108 Yuan,equaling to increasing 1.2% per year.It indicates that the ecological projects carried out now improve the ecosystem service ability.But the farming-pasture zigzag zone in Hebei Province is a typical environmental frangibility area,so it need to strengthen the protection of life-form and treatment of desertification,and enhance the power of returning cultivated land to forestland or grassland in the future.
