| 1 | Soil microbial activity and nutrients of evergreen broad-leaf forests in mid-subtropical region of China显示文摘To better understand the effects of forest succession on soil microbial activity, a comparison of soil microbial properties and nutrients was conducted between three forest types representing a natural forest succession chronosequence. The study compared a pine(Pinus massoniana) forest(P_F), a pine and broadleaf mixed forest(M_F) and an evergreen broadleaf forest(B_F), in the Yingzuijie Biosphere Reserve, Hunan Province, China.Results showed that soil nutrients in the M_Fand BFplots were higher than in the P_Fplots. The range in microbial biomass carbon followed a similar pattern with B_Fhaving the greatest values, 522–1022 mg kg^-1, followed by M_F368–569 mg kg^-1, and finally, P_F193–449 mg kg^-1. Soil nutrients were more strongly correlated with microbial biomass carbon than basal respiration or metabolic quotient. Overall, forest succession in the study site improved soil microbial properties and soil fertility, which in turn can increase primary productivity and carbon sequestration. | Zhangquan Zeng Silong Wang Canming Zhang Hong Tang Xiquan Li Zijian Wu Jia Luo | 2015 | Journal of Forestry Research2015，26，3： | 5 |
| 2 | Inheritance of resistance to Helicoverpa armigera of 3 kinds of transgenic Bt strains available in upland cotton in China显示文摘There are 3 kinds of transgenic Bt strains, Shanxi 94-24, Zhongxin 94, and R19, in upland cotton in China. Their transgenic Bt insect-resistance cultivars or hybrids have been developed and grown by farmers. Genetic studies indicate that the resistance of the 3 transgenic Bt cotton strains to Helicoverpa armigera is controlled by one pair of non-allelic dominant genes. Linkage relationship between the resistant genes of R19 and Shanxi 94-24 transgenic Bt strains shows that they may be inserted in the same chromosome. FT hybrids crossed among the 3 strains show that high levels of protection from feeding damage are the same as that of their parents. Therefore, there is no co-suppression phenomenon in many transgenic plants. The results presented here afford a fundamental reliance in developing transgenic Bt insect-resistant cultivars and exploiting the heterosis of hybrids in upland cotton. | TANG Canming SUN Jing ZHU Xiefei GUO Wangzhen ZHANG Tianzhen SHEN Jinliang GAO Congfen ZHOU Weijun CHEN Zhixian GUO Sandui | 2000 | Chinese Science Bulletin2000，45，4： | 3 |

| 5 | Carbon Reserve Characteristics of Arbor Layer in Mid-subtropical Evergreen Broad-leaved Forest显示文摘In this paper, secondary forest of Pinus massoniana , coniferous-broad-leaved mixed forest and broad-leaved evergreen forest were taken as research objects, to explore carbon reserve of arbor layer and its spatial distribution characteristics. At different succession stages, the sequence of organic carbon content in each organ was secondary forest of P. massoniana > coniferous-broad-leaved mixed forest> broad-leaved evergreen forest. Carbon reserve of arbor layer was the highest in broad-leaved evergreen forest, which was 129.34 t/hm 2, followed by coniferous-broad-leaved mixed forest (95.83 t/hm 2), and the minimum was 85.27 t/hm 2 in secondary forest of P. massoniana . In each stand type, the sequence of carbon reserve of each organ in arbor layer was trunk>root>branch>leaf>bark. Carbon reserve of arbor layer mainly concentrated in trunk, and the proportion to carbon reserve of arbor layer declined from secondary forest of P. massoniana to broad-leaved evergreen forest, while it had increasing relationship in root. In secondary forest of P. massoniana , coniferous-broad-leaved mixed forest and broad-leaved evergreen forest, individual with the diameter more than 20 cm accounted for the majority of carbon reserve in the arbor layer. | Zeng Zhangquan Wang Ying Li Minghong Tang Hong Yang Rui Zhang Canming Zeng Xiahui | 2019 | Meteorological and Environmental Research2019，10，4： | 0 |
| 6 | Biomass Characteristics of the Arbor Layer in Different Stands of the Evergreen Broad-Leaved Forest显示文摘In this paper, the Pinus massoniana forest in the early stage of succession, the coniferous broad-leaved mixed forest in the middle stage of succession, and the evergreen broad-leaved forest in the late stage of succession were studied, and the biomass and its spatial distribution characteristics of the tree layer in different succession stages of the ecosystem were discussed. The results showed that the biomass of the arbor layer was the highest in the evergreen broad-leaved forest, which was 292.51 t/ hm2, followed by the coniferous and broad-leaved mixed forest, which was 206.87 t/hm2, and the Pinus massoniana forest, which was 171.76 t/hm2. The biomass of trunks accounted for the largest proportion in the total biomass of the arbor layer, which reduced from the Pinus massoniana forest to the evergreen broad-leaved forest. The proportion of the biomass of roots in the total biomass of the arbor layer increased from the Pinus massoniana forest to the evergreen broad-leaved forest. The biomass of the diameter class above 20 cm in the Pinus massoniana forest, the coniferous and broad-leaved mixed forest and the evergreen broad-leaved forest accounted for a large proportion of total biomass. | ZENG Zhangquan TANG Hong LI Minghong YANG Rui ZHANG Canming WANG Ying ZENG Xiahui | 2019 | Journal of Landscape Research2019，11，3： | 0 |
| 7 | Construction of Biomass Model of Phylloctachys pubescens Forest in Hunan显示文摘To accurately calculate carbon fixation capacity of P.pubescens forest in Hunan Province and promote the balanced and stable development of P.pubescens forestry in Hunan Province,standard sample plot was set in major producing area of P.pubescens in Hunan Province,and biomass of 258 P.pubescens was measured according to DBH and age class.Multivariate regression method was used to establish univariate (DBH as independent variable) and bivariate (DBH and age class as independent variables) models of total aboveground biomass and organ biomass of P.pubescens .Model evaluation and test showed that each model accorded with the applicable precision and had the appropriate prediction level. | Zeng Zhangquan Wang Ying Li Minghong Tang Hong Zhang Canming Yang Rui Zeng Xiahui | 2019 | Meteorological and Environmental Research2019，10，3： | 0 |
