In rectent years numerous studies have focused primarily on the sen,ices of natural ecosystems. This paper expands the scope of this field from natural ecosystems to semi-natuval ecosystems, i.e. cropland ecosystems, which are closely associated with human productivity and life. Taking Huantat County in Shandong Province as an example, the vegetation.based services of winter wheat/summer maize rotation systems and carton cropland ecosystems were systematically analyzed, including the material production, carbon dioxide fixation, oxygen release, water conservation, and nutrient recycling. These services were then evaluated in terms of economics through the applications of a market value technique, a substinaion engineering method and a shadow price method. The results indicated that the total economic value of cropland ecosystem vegetation.based services in Huantai County is 124.827.3 ×10^4 yuan. which is equivalent to 15.63% of the GDP of Hnantat County (798, 491 × 10^4 yuan), Among these services, the gas regulation value is 82.698.3 × 10^4 yuan (66.25%), the material production value is 38.049.4 × 10^4 yuan (30.48%), the nutrient cycling value is 3257.3 × 10^4 ynan (2.61%), and the water conservation value is 822.3 × 10^4 yuan (0.66%). In addition, through the comparison between winter wheat/summer maize rotation systems and cotton cropland ecosystems, we conclude that the economic value of vegetation-based services provided by the former is much higher than that of the latter, which could provide a scientific guideline for adjusting the agricultural structure, Our study may facilitate the conservation of cropland ecosystems and promote effective use of vegetation-based services to achieve sustainable development of agriculture and guarantee nationwide food security.展开更多
