【摘要】 本研究地点选在东北林业大学实验林场，研究人员圈定了7个树种的7块样地，共700个树木样本。利用ArcView和CITYgreen模型，结合遥感图像判读和样地调查，构建了7样地的管理信息系统。同时对样地内树木的生长状况、对大气污染物的吸附情况、碳储存碳吸收及相关的经济价值进行了现状评价，并利用模型的模拟预测功能，对10、20、50年后的相关指标进行了模拟预测。 研究得出以下主要结论：1、构建了7样地的管理信息系统，方便了日后对项目的查询、管理及快速更新。2、植被所发挥的生态效益，极大程度取决于其本身的绿量多少。3、作为城市绿化树种，糖槭和白桦在各项指标的评价中都明显优于其他研究树种，为绿化树种的选择提供了可靠依据 4、对相关的生态效益及其所创造的经济价值，研究得出了具体数值，为城市森林由定性向定量化研究提供了理论和技术上的依据。更多还原

【Abstract】 This research place is selected in the forest farm of the experiment of Forestry University of the Northeast, researchers draw a circle to approve 7 pieces of ground of 7 seeds , amount to 700 trees samples. Utilize ArcView and CITYgreen model, combining picture interpretation remote sensing and investigate of kind of ground , structure the management information system of 7 kinds of ground. At the same time to the growth states of the trees in a kind of ground, store carbon absorbing and relevant economic worth and appraise the current situation to absorbing the situation , carbon of air pollutant, and utilize simulation of the model to predict the function , imitate predicting to the relevant index 10 , 20 , 50 years later.Can work out the following main conclusion: 1, Structure the management information system of 7 kinds of ground , the convenient inquiry , management and upgrading fast to the project in the future . 2, The ecological benefits given play to of the vegetation, the great degree depends on how much its one’s own green quantity is. 3, As city afforestation seeds, candy tool and white birch superior to other research seeds obviously in every appraisal of index, in order that the choice of afforesting the seeds has been offered the reliable basis 4, to relevant ecological benefits and economic worth created, work out concrete number value , is it is it is it offer theory and basis of technology to study to take for city forest to ration to determine the nature.更多还原
