The community structure, tree species composition, biodiversity and diameter structure of Castanopsis carlesii forest (8-year old) by AMPR(artificial measures promoting regeneration) of first generation after clear-cutting are similar to the second generation(6-year old).
皆伐形成的一代(8a生)和二代(6a生)人促米槠林的群落结构、组成树种、物种多样性、直径结构等均相近;但一代人促米槠林以有性(实生)起源为主,二代人促米槠林以无性(萌芽)起源为主,二代林分生产力明显大于一代林分,充分体现萌芽更新的早期速生性。
3.

经我们在长武王东沟试验区多年试验研究表明:皆伐萌蘖更新是改造低产值刺槐林的有效途径。
3) clear cutting
皆伐
1.
Potential effect of destructive clear cutting on forest soil composition;
皆伐作业对林地土壤因子的影响
2.
The population structure, growth and reproduction of Potentilla glabra shrubs under primary Picea balfouriana forest and on nearby 7-year-old cutover were investigated to explore how clear cutting affected the understory shrub population developement in the eastern Qinghai-Tibetan Plateau.

5) clear felling
皆伐
1.
clear felling slash, cultivating rubber,slash-and-burn and cultivating sugarcane and sweet potato,etc.
利用海南岛吊罗山林区内的生态定位观测站近3a的定位观测数据,和定期采样进行的土壤物理性质测定,分析了不同的次生林砍伐程度和利用方式(包括次生林对照、择伐50%、择伐70%、皆伐迹地、垦植橡胶和刀耕火种垦植甘蔗、蕃茨等作方)对土壤温度、土壤含水量、土壤团聚结构、土壤机械组成、土壤容重、孔隙度和土壤持水特性等土壤主要物理性质的影响,结果显示,热带次生林的过度砍伐和不合理的刀耕火种,严重地影响了土壤主要的物理性质,导致土壤表层温度升高、温差加大,土壤含水量和持水性能下降,土壤结构受破坏,土壤粘粒流失和向砂砾化发展等等,造成了土壤生态环境的恶化,直接影响了森林的再生和林地的开发和利用,其中尤以皆伐迹地和刀耕火种的影响最为严重。
