- Abstract:
-
To supply consultation to the city eco-civilization, the ecological service value of Xuzhou City was evaluated and predicted dynamically by using the Markov chain model based on the five periods of land use information of remote sensing images. The results show that the land use changed greatly from 1995 to 2010. Specially,the farmland area of Gulou, Yunlong and Quanshan districts decreased from 53.5%, 69.02% and 40.04% to 34.4%, 46.18% and 26.27%, as a result, the total ecosystem service value also decreased from 292, 175 and 151 million yuan to 155, 106 and 126 million yuan. When the steady state of ecology was reached, the ecosystem service values of Gulou, Yunlong and Quanshan districts grew to 299, 164 and 147 million yuan due to the increase of farmland, forest and water areas. Results indicate that it is very important for ecological civilization to control the transformation of farmland, woodland and waters to building sites.
