By means of the quantitative theory I,the relationships between environmental theory 1,the relationships between environmentalfactors and the density chang during self-thining of Cunninghamia lanceolata plantation were set up,and themain environmental factors affectes on self-thinning significantly,which are altitude,situation of slope andmean diameter at breast height,were gained.

提出森林自疏过程中密度随时间变化的调节模型、提出并阐述应用于森林自疏规律研究的基于改进单纯形法的网络模型的基本原理和算法，两方法经山杨林、云南松林的自疏过程密度随时间变化资料进行验证，证明两方法更合理且适用性更强，进而将其应用于杉木林自然稀疏规律模拟，模拟残差平方和仅为前人模型的92.8％和56.1％，效果较理想。

It is learned that the city will be blocked in accordance with the combination of thinning approach, strengthen Zhuozhou City, Hebei Province, Sanhe City, such as brothers and city and county links, from "order agriculture" and "Beijing vegetables green channel" model, dredge sand and gravel production from other provinces , transport channels, from the source to curb illegal sand mining activities in the city; At the same time, city, district levels should be taken by way of a joint law enforcement, focus on time to carry out special rectification, and resolutely clamp down on illegal sand mining, illegal mixing station, component plants, to ensure the city's major construction projects, the protection of the capital of the environment.

据了解，城市会被拦截按照间伐相结合的办法，加强涿州市，河北省三河市，如兄弟和市，县的联系，从&订单农业&和&北京蔬菜绿色通道&模式，疏浚沙石生产，其他省，运输渠道，从源头上遏制非法采砂活动的城市；同时，市，区两级应采取的方式，联合执法，重点对时间进行专项整治，坚决取缔非法采砂，非法搅拌站，构件厂，以确保城市的重大建设项目，保护首都的环境。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
