Economic value of agroecosystem service in typical wind-erosion region of transition zone between agriculture and pasture

Abstract

Abstract: The economic evaluation on ecosystem services has become a frontier of ecological studies.The concept and economic values of ecosystem services have been thoroughly discussed over the past decade, mostly on natural ecosystems and less on agroecosystems.In this paper,the agroecosystem services and their economic value were estimated in wind-erosion region near the northern foot of Yinshan mountain in Inner Mongolia.The results showed that the total economic value in RMB of agroecosystem services in this area was about 465.45 billion yuan.In this amount,estimations for production service amounted to 0.06%,for soil protection to 9.7%,for water holding capacity to 0.09%,for climate regulation to 0.84% and for nutrient recycle to 89.27%.

Key words: Southern area of Jiangsu Province, Paddy field, Fertility evolution, Nutrient balance, Reasonable fertilizer application amount
