发布时间：2019-03-07 23:13
【摘要】：研究目的:探析不同土地利用模式下碳储量的空间差异特征,为优化城镇土地利用及其生态效益提供参考。研究方法:InVEST碳储量修正模型、归一化不透水地表指数(NDISI)和层次聚类分析。研究结果:(1)2014年北京市三山五园地区碳储量为23.31×10~4 t,单位土地面积平均碳储量32.28 t/hm~2;各街道碳储量差异明显。(2)以NDISI变化率表征土地利用开发强度,1992-2014年间上地街道开发强度最高,青龙桥街道(颐和园)开发强度最低。(3)该区各街道碳储量与其区位、用地结构及开发建设模式密切相关,开发建设活动并非一定会降低城镇土地碳汇能力。研究结论:土地利用模式影响城镇土地碳储能力,加强城镇土地利用模式与生态效益研究,有助于合理制定城镇土地利用政策。
[Abstract]:The purpose of this study is to explore the spatial difference characteristics of carbon reserves under different land use patterns, and to provide references for optimizing urban land use and its ecological benefits. Methods: InVEST carbon reserve correction model, normalized impermeable surface index (NDISI) and hierarchical clustering analysis. The results are as follows: (1) in 2014, the carbon storage in Sanshanwuyuan area of Beijing was 23.31 脳 10 脳 10 ~ 4 t, and the average carbon storage per unit land area was 32.28 t / hm ~ (2); (2) the intensity of land use and development was characterized by the change rate of NDISI, and the development intensity of Shangdi street was the highest in 1992 / 2014. The development intensity of Qinglongqiao Street (Summer Palace) is the lowest. (3) the carbon storage of every street in this area is closely related to its location, land use structure and development and construction mode, and the development and construction activities will not necessarily reduce the carbon sink capacity of urban land. The conclusion is that the model of land use affects the carbon storage capacity of urban land, and strengthening the study of urban land use pattern and ecological benefit is helpful to formulate the policy of urban land use reasonably.
