Based on the different original forest land types, the hill countries of Huzhou City Zhejiang Province, which have been 7 years of closing the land for reforestation, can be divided into three closing hill types of bare rock, barren hill and open forest. The authors compare the stands which have closed hill 7 years with the stands which have closed hill 20 years, and discuss the tree species, community structural characters, succession patterns and biomass. The facts show that closing the land for reforestation is an effective messure with low cost, good result and to re-cove quickly forest vegetation.

浙江省湖州市丘陵地区封山育林7年,按原造林地类型不同,可划分为露岩、荒山和疏林封山类型。作者把封山育林7年的林分与封山育林20年的林分加以对照,论述了各封山类型林分的树种组成、群落结构特征、演替规律和生物产量。实践证明:封山育林是一种成本低、效果好、能迅速恢复森林植被的行之有效的营林手段。

In this paper, lodging shoots in selective cutting unevenaged plantation of fishscale bamboo located in the Longhekou of Shucheng county, Anhni province, were studied.

In this paper, lodging shoots in selective cutting unevenaged plantation of fishscale bamboo located in the Longhekou of Shucheng county, Anhni province, were studied. The results, based on surveying from 1,267 m~2 of 30 plots and 19 sample strips along an investigation line of 3,600 m, showed as follows: 1. The number of lodging shoots in the stands where bamboo shoots sprout thickly or plotting are more than those in which bamboo shoots grow singly or separately; 2. The number of lodging shoots in the opening forest and thin stocked stands resulted by selective cutting are more compared with those in the well distributed bamaoo stands; 3. Lodging shoots grown in the border of stand are more, but less within stands; 4. Lodging shoots grown in the stands protected by shelter-belts are less, otherwise are more; 5. Lodging shoots having mother bamboo with larger diameter class are mere than those with smaller diameter class; 6. The number of lodging shoots in the fertile stands are more, but less in the poor stands; 7. The number of lodging shoots grown in the stands near resident areas are more, compared with those growing in off resident areas.
