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。

The rainy Season was in the mean Time upon me, when I kept more within Doors than at other Times; so I had stow'd our new Vessel as secure as we could, bringing her up into the Creek, where as I said, in the Beginning I landed my Rafts from the Ship, and haling her up to the Shore, at high Water mark, I made my Man Friday dig a little Dock, just big enough to hold her, and just deep enough to give her Water enough to fleet in; and then when the Tide was out, we made a strong Dam cross the End of it, to keep the Water out; and so she lay dry, as to the Tide from the Sea; and to keep the Rain off, we laid a great many Boughs of Trees, so thick, that she was as well thatch'd as a House; and thus we waited for the Month of November and December, in which I design'd to make my Adventure.

雨季快到了，那时我们大部分时间都只好呆在家里，为此，我得先把我们的新船放置妥当。我把船移到从前卸木排的那条小河里，并趁涨潮时把它拖到岸上。我又叫星期五在那里挖了一个小小的船坞，宽度刚好能容得下小船，深度刚好在把水放进来后能把船浮起来。然后，趁退潮后，我们又在船坞口筑了一道坚固的堤坝挡住海水。这样，即使潮水上涨，也不会浸没小船。为了遮住雨水，我们又在船上面放了许多树枝，密密层层地堆了好几层，看上去像个茅草屋的屋顶。就这样，我们等候着十一月和十二月的到来：那是我准备冒险的日期。
