Analysis on Evaluation of Ecological Construction Efficiency over 30 Years in Changzi County of Shanxi Province
摘要
Abstract
By using the ecosystem service value as the index of regional ecosystem service function,the change of land use type and ecosystem service functions of Zhangzi County from 1985 to 2007 were analyzed.According to research achievement and the specific situation of Zhangzi County,this paper adjusted the unit ecosystem service value of different land use types.Based on this,the change in ecosystem service value of Zhangzi County resulted from the land use change was analyzed.The results show that the land use structure of agricultural,forestry and animal husbandry changes,the areas of farmland reduced by 33%,grassland is next,reduced by 32%.The areas of woodland had relatively substantially increased by 113%,the largest increase in orchard occurred,increased 31 times.The total service value of ecosystem increased by 44.54 million Yuan,resulting from the increase of woodland and garden area.The ecological environment construction of the county has made a great achievement,has stimulative effect on the improvement of the ecological environment.关键词
