摘要
利用遥感手段并结合地面调查，针对广州市这一区域进行森林空间分布和时间序列的分析，然后依据研究区实地情况构建森林固碳释氧价值核算模型，并将核算结果与区域发展水平进行时空相关分析，探讨广州市森林生态系统固碳释氧价值时空动态变化及其与人口、经济、社会发展水平、可持续水平之间的相关关系。结果表明：1995～2000年森林固碳释氧价值增加了5．79亿元，森林仍然起到碳汇的作用，但其空间分布极不平衡，呈现北高南低局面；森林固碳释氧价值的增长落后于人口、经济的增长，社会发展水平指数与森林固碳释氧价值的增长速度为负相关关系，入口及经济的迅速增长在一定程度上阻碍了森林固碳释氧价值的增加。
This study emphasized to find the forest spatial distribution and time series analysis tot Guangzhou using remote sensing technology and the field survey data. Then use the new model which constructed based on the study area actual conditions to account the changes of the value of the forest carbon fixation and oxygen release. The improved model was developed to investigate the changes of the value of the forest carbon fixation and oxygen release. Subsequently, the distribution of the value of the forest carbon fixation and oxygen release and its correlation analysis with regional development indices, such as population, economic, social development level and sustainable development level, were also studied. The result indicates that the value of the forest carbon fixation and oxygen release in 2000 is 0. 579 billion yuan more than that of 1995, and the forest still playing a role of carbon sink. But it＇s spatial distribution extremely imbalance, presents high in the north and low in the south of this study area. Secondly, the development of the value of the forest carbon fixation and oxygen release was far lower than that of population and economy. There are positive correlation between the index of social development level and the development of the value of the forest carbon fixation and oxygen release. To some extents, the rapid increase of population and GDP influence the increase of the value Of the forest carbon fixation and oxygen release.
