【摘要】：研究目的:探析不同土地利用模式下碳儲量的空間差異特征,為優(yōu)化城鎮(zhèn)土地利用及其生態(tài)效益提供參考。研究方法:InVEST碳儲量修正模型、歸一化不透水地表指數(shù)(NDISI)和層次聚類分析。研究結果:(1)2014年北京市三山五園地區(qū)碳儲量為23.31×10~4 t,單位土地面積平均碳儲量32.28 t/hm~2;各街道碳儲量差異明顯。(2)以NDISI變化率表征土地利用開發(fā)強度,1992-2014年間上地街道開發(fā)強度最高,青龍橋街道(頤和園)開發(fā)強度最低。(3)該區(qū)各街道碳儲量與其區(qū)位、用地結構及開發(fā)建設模式密切相關,開發(fā)建設活動并非一定會降低城鎮(zhèn)土地碳匯能力。研究結論:土地利用模式影響城鎮(zhèn)土地碳儲能力,加強城鎮(zhèn)土地利用模式與生態(tài)效益研究,有助于合理制定城鎮(zhèn)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.
