Study on stand Diameter Structure Model
Hui Gangying, Sheng Weitong
1995, 8(2): 127-131.
Abstract:
Combined theoretical analysis with actual tests,a new prediction method(L-PRM) for stand diameter distribution is presented. The method takes the distributed law of different trees in stand as a question of biological interpopulation distribution,and stand diameter distribution is expressed by means of the famous logistic equation──interpopulation dynamic model.The prediction can be made by the two-point recovery and difference restoration.The results proved to be satisfactory after the examination in Cunninghamia lanceolata forest.

Chu Guozhong, Peng Changgen, Zhang Changgen, Zeng Guomin, Xia Liangfang, Chen Yi
1995, 8(2): 132-138.
Abstract:
bird species under 30 families and 11 orders(4 suborders)were found inthe area around the Nianzhu Forest Farm from March 1992 to DeC.1993.Most of them,92 species,74% of all species)belong to Passeriformes, in which 45 species of Muscicapidae,49% of those of Passeriformes are included. The avifauna is mainly composed of Oriental element. Among the 91 breeding species,there are 72 Oriental elements accounting for 79% of the total breeding species.The summer visitors stay here for 193 days(April 17~Oct.27),the winter visitors for 250 days(Aug. 27~May 4). The travellers passed by in spring or autumn,so the number ofbird species present is more abundant at this time than those in the other two seasons.
Standardiztion of Landsat TM Imagery for Forest Resources Dynamic Change Monitoring
Zhang Yugui
1995, 8(2): 139-144.
Abstract:
The paper described an atmospheric correction method for LANDSAT TMimagery. The dynamic change monitoring of vegetation coverage and the variability of atmo-spheric conditions necessitate the normalization or standardization of satellite imagery. The atmospheric parameters at overpass time were evaluated through interpolation among localmeteorological records. The digital model is used to adjust the variation of illumination parameters with elevation,and to correct for the topographic effect. The corrected imagery canbe suitably used for multitemporal monitoring of renewable resources.
A Study on the Biology and Ecology of the Larch Sawfly Pristiphora erichsonii and Its Control
Zhou Shuzhi, Huang Xiaoyun, Zhang Zhen, Wang Hongbin, Zhang Peiyi
1995, 8(2): 145-151.
Abstract:
Pristiphora erichsonii(Htg.)has one generation a year in Beijing area with prepupae overwintering in cocoons in the litter and soil under the tree crown. The effective accumulative temperature for the eggs and larvae was studied by means of linear regression method,which were 110.4586 and 383.5238 day·degree. The optimal developmental tem-perature for larvae ranges from 16~20℃. The average number of egg mass per twig is 0.73 at the border of the larch forest or at the western and northern part of the tree,while 0.3 per twig inside the forest or at eastern or southern part of the trees. The parasitic rate of co-coons reached 83.23%. The effects of abiotic and biotic factors on its occurrence were discussed. According to the results from indoor and field control experiments using Beauveria,B. t.,and netomopathogenic nematodes as control agents, it is assumed that the enmatodes are the best biocontrol agents which can infect the larvae on the trees and mature larvae on the ground with a mortality of 80%~100%. The mortality caused by Beauveria and B. t. are 28%~52%and 5%~27%,respectively, with a mortality as high as 98%~100%,Dimilin is also a good insecticide to control the sawfly.

Zheng Dezhang, Liao Baowen, Zheng Songfa, Xu Dagui, Han Zhi
1995, 8(2): 152-158.
Abstract:
Under better condition of protection the mangrove communities in Qinglan Harbour present two-layer structures of tree and shrub, in which tree layer is 4~8 m and shrub layer is 0.4~1.2 m in height.The biomass of stauding trees above ground decreases with the increase of tree height i.e. 50% in 0~2m,40.3% in 2~4m,7% in beyond 4 m. It was known from the investigation that after the mangrove communities were destroyed and interfered by human beings, they are decreased by 1611 hm2,in the period of 27 years,and turned into brushes with only one layer structure,which is lower in biomass and productivity only 9.6~14.3 t/hm2 and 1.1~2.0 t/(hm2·a)respectively. The study indicated that the biomass and net productivity of Bruguiera gymnorhiza stand were 91.5 t/hm2, and 4.7 t/(hm2·a), and they will increase to 350.7 t/hm2 and 13.5 t/(hm2·a)in the end of the coming six years.
A Study of Fertilization Effect on Young Trees of Eucalyptus urophylla
Zhou Wenlong
1995, 8(2): 159-163.
Abstract:
Fertilization on young trees of Eucalyptus urophylla lay emphasis on the application of base fertilizer. There have been obvious fertilization effects of fast growth in the early stage for young trees of E.urophylla if applying enough amount of base fertilizer before planting.A trial of amount of fertilizer applied and fertilizer ratio for young trees of E.urophylla has been carried out in 1992.The results show that the effects of mixing N,P and K fertilizer used as base fertilizer are significant. The mean tree height and DBH of nine fertilizer treatments at the age of 23-month-old in the trial are 6.43 m and 6.86 cm respectively,and the mean tree height,DBH and volume per hectare for the ninth treatment(N100P150K50)are respectively 7.73 m,8.0cm,and 26.335 m3,which are respectively 293.92%,408.16% and 4 931.6% of the control treatment (no fertilizer treatment) which is of 2.63 m tree height,1.96 cm DBH and 0.534 m3 for volume per hectare. The audio-visual analysis of tree height, DBH and volume per hectare show that the N100P150K50 treatment is the optimum recipe.The contents of nutrient elements in foliage are also obviously different among the treatments.

Study on the Seedbed Density of Growing Slash Pine Seedling
Jiang Jingmin, Hu Shicai, Xia Xifeng
1995, 8(2): 199-204.
Abstract:
The bareroot seedling quality of slash pine(1~0) grew at different nursery density levels was studied,and their economic benefits analyzed. It showes that seedbed density is a decisive factor to seedling quality which decreases with the increase of density. The yield of grade l seedling are the highest at 111/m2,and the nurnber of grade 2 and 3 seedlings increase by larger density,the percentage of the grade 3 seedling reach 15% of the permissive limit of the national seedling production standard at 167/m2. If only grade 1 seedling in qualified,the output/input is the highest at 69/m2; when grade 1 and 2 seedlings are used for plantation and give different prices, the output/input is highest at 111/m2. The practice of outplanting the ungraded seedlings(grade 3) which leads to higher density,at which the benefit of production is highest but the seedling quality is worst.A comprehensive survey of seedling quality, yield of qualified seedling and the economic benefit has been made,and the rational seedbed density would be 70~110/m2.
A study on Bioligical Characteristic of Shorthorned Beetle
Yang Chuncai, Liang Hong, Tang Yanping
1995, 8(2): 205-209.
Abstract:
Oberrea ferruginea is a common boring beetle that mainly attacks Euonynls japonicus. The beetle completes its life cycle in one year in Hefei area. The beetle larva over-winters in limbs or stems and starts to pupate in the last ten days of April. Adults emerge inthe second ten days of May,then lay eggs in the first or second ten days of June. Larva startsto overwinter in the second ten days of October. Its occurrence is mainly influence by light.Femals lay their eggs at different locations due to the different level of tree vigour. The damage caused by the beetle is different in various positions of the tree. The major controlmethod is to prune branches,but chemical control for the beetle is not effective.

Xie Hefeng, Yu Zhongkui, Chen Yishan, Zhang Qiwen, Xu Hong
1995, 8(2): 226-229.
Abstract:
The growth of Populus deltoides and Populus×euramericana clones from thegene-pool in Changqing County,Shandong Province is studied. A significant variance is observed in growth among clones. The broad-sense heritability for DBH and height are higherfrom the fourth year on,and till the tenth year they remain above 0.7. There are differentcharactertstics of growth and genetic variation between P. deltoides and P. × euramericana. The growth in DBH and height at early stage of P.euramericana is superior to P. deltoides, till the tenth year, both are basically the same. Average heritability of DBH is higher thanthat of height for P. × euramericana, but it is contrary for P. deltoides. The growth for P. deltoides shows significant negative correlation to the original latitude.
