Beijing environmental problems hold severe, and atmospheric and water pollute, soil and water loss, hot island and yawp are leading problems,and take on territorial characteristic. Based on research on relativity between urban forest and these environmental problems, urban forest can effective improve environmental quality in Beijing. And for the aim of improve environmental quality, Beijing forest overlay should attain 35% at least in citywide range, and local-areas being severe environmental problem should be provided with higher forest overlay.5. Through the study on urban forest needed capacity, Beijing's forest coverage is up to par in citywide range, but montanic forest coverage, plain covered with trees and average forest area are lacking, and CO2 and O2 balance is incapable;form the point of heat and balance CO2 and O2 balance,urban forest the city zone and suburb is lack. There is urban forest developmental potential space,but the city zone and suburb area need be compensated form urban forest in circumjacent region.6. On the based of the above results and ecological network system, the author drived whole region into city area, plain and mountain area are needed at the point of planning thoughts of running-through forests and water .

根据城市森林与北京市主要环境问题的相关性分析，城市森林在改善这些环境问题中具有重要的作用，为有效改善这些环境问题，整个北京市域范围内森林覆盖率至少达到35%，并且分布比较均匀，环境问题严重的局部区域需要不同程度增加森林覆盖率。5、通过对北京市城市森林需求量研究发现，虽然在市域范围内北京森林覆盖率达到了国家标准，但是山区森林覆盖率、平原林木覆盖率、城区人均森林面积不足；从区域热平衡和碳氧平衡角度分析，城区和郊区不能满足本区域的城市森林需求量，虽然北京市城市森林具有一定的发展潜力，整体上基本可以满足城市需要，但是这些区域需要依靠周边区域城市森林的补偿。6、根据以上的研究结果，以中国森林生态网络体系建设的点、线、面布局理念为指导，以&林网化——水网化&作为优化理念，将北京市整个市域划分为城区近郊区及其辐射区域，平原区和山区三大区域，依据三大区域特点进行城市森林布局优化。

General analysis indicates that Myriophyllum spicatum L.Panicle shape of the absorption of chromium Cr6 + concentration and treatment exist between the concentration of significant positive correlation with Myriophyllum spicatum L.can pollute the environment in better enrichment of chromium, the background environment The higher concentration levels of heavy metals, plant accumulation of heavy metals in higher concentration levels, the application of plant technology for the repair of heavy metal pollution on the environment to provide a scientific basis on Myriophyllum spicatum L. of heavy metal pollution of wetland restoration has great potential.

综合分析表明，在一定范围内，穗状狐尾藻对铬Cr6+的吸收富集含量随处理浓度升高而增大，说明穗状狐尾藻在污染环境中能较好地富集重金属铬，从而得出在一定范围内，环境背景中重金属含量水平越高植物富集重金属的含量水平也越高的结论，这就为应用植物技术修复重金属对环境造成的污染提供科学依据，而穗状狐尾藻对湿地重金属污染具有较大的修复潜力。
