| 摘 要： | 利用美国宇航局提供的MODIS产品中的GPP,通过ERDAS软件投影转换、影像裁切等功能,采用光能利用率模型估算区域GPP,NPP,NEP,并与GIS结合,实现各级氧气生产量的空间表达和总量计算。本文以哈尔滨市为例,研究2008年哈尔滨市区域氧气生产量。提出的估算氧气方法在此类研究中尚属首次,为区域氧气生产量的估算提出了新的研究思路,同时为评价人类生活环境质量提供了依据。

| Abstract: | Utilizing the GPP product in the MODIS product provided by NASA and relying on the software projection conversion and image clipping function of ERDAS software,the spatial expression and calculation of total oxygen output at all levels is achieved by estimating the regional GPP,NPP,and NEP through combining C-FIX model with GIS technology.Taking Harbin city as a case study,this paper studies the oxygen output of Harbin urban area in 2008.The method of estimating oxygen output proposed in this paper is the first in similar studies,which provides new ways of thinking in the study of regional oxygen output estimation and the basis for assessing environmental quality of human life. |
