With these equations, the aboveground biomass of Masson pine forest, slash pine forest and Chinese fir forest were estimated, in addition to the allocation of aboveground biomass.
      
The above-ground biomass of Masson pine forest, slash pine forest and Chinese fir forest was 83.6, 72.1 and 59 t/hm2 respectively, and the stem biomass was more than the foliage biomass and the branch biomass.
      
The communities of microorganisms involved in the nitrogen and carbon cycles are dominated by prototrophic forms in the normal fir forest and by pedotrophic forms in the forest defoliated by pests.
      
In the southern-taiga low grass-green moss fir forest completely defoliated by the Siberian moth, the rate of soil respiration in the third year after the pest population outbreak was 1.5 times higher than in an undisturbed tree stand.
      
The rate of carbon emission from the soil in the defoliated forest was 41.7 kg/ha per day, compared to 28.3 kg/ha per day in the undisturbed fir forest.

Based on the biomass investigation, soil respiration and plant photosynthesis measurement of dominant trees in Hailuogou valley of Mt. Gongga, Southwest China, the carbon(C) storage, absorption and release for several typical woodland in sub-alpine zones have been discussed. For Abies fabri forest of 3000 m above sea level, the C storage amount is 177.4 t/hm 2 for plant above ground surface and 143.2 t/hm 2 for soil. The annual gross C fixed by vegetation photosynthesis is 20-24 t/hm 2 . The C release by canopy respiration is 3.0-5.5 t/hm 2 for arbors and 10-19 t/hm 2 for soil and roots. The total annual net C fixed in forest ecosystems is about 6.0-7.1 t/hm 2 . At lower position, the woodland released C amount is higher than that of woods at higher place. The C fixed capacity of renewed forest with middle-aged trees is higher than that of mature forest.

根据贡嘎山海螺沟内5种主要林地上的生物量调查、土壤呼吸和光合作用测定,研究亚高山地区典型林带上C的存贮、吸收和排放关系。对于海拔3000 m附近的峨眉冷杉林,其地上和地下C贮量分别为177.4 t/hm2和143.2 t/hm2,森林光合作用吸收的C量在22~24 t/hm2·a之间,通过呼吸释放C量为3~5.5 t/hm2·a (乔木冠层) 和10~19 t/hm2·a (地面土壤及根系),年光合作用净固定的C为7.05 t/hm2。低海拔处生态系统C的呼吸量较大,100a以内的中幼龄树木固C能力高于成熟林的固C作用。林地在成为过熟林之前主要还是C的汇,林间裸地是大气的C源。

Investigations were carried out on horizontal and vertical distributions of soil gamasida in Picea and Abies forest, Larix gmelini forest, Alnus hirsuta forest, Betula platyphylla forest and broad-leaved and Pinus koraiensis mixed forest in the Xiaoxing'anling. The results indicate that Gamasellus montanus and Zercon xiaoxinganlingensis are distributed extensively in all habitats, and only in one type of habitat has a huge variety of gamasida species and the more the species exist in the habitat, the more obvious the extensively habitats is. According to Jaccard's similarity index analysis, the soil gamasida communities in Larix gmelini forest are the most similar to those in Alnus hirsuta forest, and the soil gamasida communities in Picea and Abies forest and Alnus hirsuta forest are the least similar to those in Alnus hirsuta forest and Betula platyphylla forest. The vertical distribution of soil gamasida generally shows surface enrichment, but it is different in each habitat. The higher the organic matters and total N in soil , the more the species of soil gamasida and the bigger their populations are. Most of soil gamasida tend to live in slightly acid habitats.

对小兴安岭云冷杉林、兴安落叶松林、赤杨林、白桦林和阔叶红松林五种天然林生境土壤革螨的水平和垂直分布进行了调查研究。结果表明 ,广泛分布各生境的为峰革赛螨和小兴安岭螨 ,仅存在一种生境的种类较多 ,各生境仅存的种类越多 ,生境差异性就越明显。通过Jaccard相似性指数比较分析 ,兴安落叶松林和赤杨林生境土壤革螨群落最相似 ,云冷杉林和赤杨林生境及赤杨林和白桦林生境土壤革螨群落极不相似。土壤革螨的垂直分布总体上表现为表聚性 ,但各生境存在差异。土壤有机质和全氮含量高的土壤 ,土壤革螨的种类和数量都多。多数土壤革螨适宜在微酸性的条件下生存。
