【摘要】 近年来徐州土地利用变化很大,研究其生态系统服务价值的变化情况,可以为区域生态环境的保护和恢复提供科学依据。参照中国陆地生态系统单位面积服务价值表,利用徐州1994-2002年土地利用数据,估算了土地利用变化引起的生态系统服务价值的变化。结果表明:1994-2002年徐州耕地、林地面积减少,其余类型的面积增加,其中耕地面积减少了6.14%,林地面积减少了8.42%,该区域人文景观的影响已超过了自然景观。1994-2002年徐州生态系统服务价值增加了74.35×108元/年,水域面积增加和未利用地向林地、园地转化是生态系统服务价值增加的主要原因。更多还原

【Abstract】 There have been great changes in land use of Xuzhou City in recent years.Studies of the change of ecosystem service value in the land use can supply scientific basis for the protection and restoration of regional eco-environment.Referring to the table of Chinese land ecosystem services value of unit area and utilizing the data of land use of the city from 1994 to 2002,this paper estimates the change of the ecosystem services values caused by land use change.The study shows that in the period of 1994 to 2002 there was a decrease in the area of cultivated land and forestland but simultaneously there was an increase in area of other types of land,with the influence of artificial landscape surpassing that of natural landscape.Values of ecosystem services increased 74.35×108 yuan each year.The main reason for the increase of the ecosystem services value was the increase of water body and the transformation from unutilized land to forestland and field.更多还原
