- 摘要:
- 为城市生态文明建设提供参考，基于5期遥感数据分类的土地覆盖/利用信息，对徐州市城区生态服务价值进行动态分析，并利用马尔科夫模型对其进行稳态预测。结果表明：1995—2010年间土地利用方式发生很大变化，1995年鼓楼区、云龙区、泉山区农田占地53.5%，69.02%，40.04%，2010年分别下降为34.4%，46.18%，26.27%。生态服务价值相应的由1995年的2.92亿元、1.75亿元、1.51亿元减少到2010年的1.55亿元、1.06亿元、1.26亿元。达到稳定状态时，建筑用地面积大幅下降，农田、林地和水域面积显著增加，鼓楼区、云龙区、泉山区生态服务价值分别上升为2.99亿元、1.64亿元、1.47亿元。研究结果表明，控制农田、林地和水域等向建筑物用地转移，对加强城市生态文明建设具有重要意义。
- 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.
