| 1 | Effects of Forest Gaps on Some Microclimate Variables in Castanopsis kawakamii Natural Forest显示文摘The objective of this study was to understand the effects of forest gap and variations in different seasons, gap size, locations and diurnal variations on forest microclimate and soil water content. Spatial and temporal distribution features of air temperature (TA ), soil temperature (TS ), relative humidity (h) and soil water content (Ψ) were measured in Castanopsis kawakamii natural forest gaps created by a severe typhoon or fallen dead trees. The results showed that: (1) the variations of TA , h, and TS in four seasons were extremely significant. The variations of Ψ in four seasons were extremely significant except for those between spring and summer. (2) The diurnal variations of TA and T S were expressed with a single peak curve. The diurnal variations of h and Ψ presented a high-low-high trend. (3) The variations of TA , h, and TS were extremely significant among the large, medium and small gaps in C. kawakamii natural forest. Medium gaps had the highest TA and the lowest h while small gaps were just contrary to medium gaps. The variations of Ψ were extremely significant for large, medium and small gaps except those between the medium and large gaps. (4) The TA , h, TS and Ψ were decreased from the gap center, canopy gap, expanded gap to understory. These results will help further our understanding of the abiotic and consequent biotic responses to gaps in the mid-subtropical broadleaved forests, which also provide a theoretical basis for the scientific management and population restoration of C. kawakamii natural forest. | HE Zhongsheng LIU Jinfu WU Caiting ZHENG Shiqun HONG Wei SU Songjin WU Chengzhen | 2012 | Journal of Mountain Science2012，9，5： | 17 |
| 2 | A mathematical modeling study of the HIV epidemics at two rural townships in the Liangshan Prefecture of the Sichuan Province of China显示文摘Background:As a response to a severe HIV epidemic in the Liangshan Prefecture,one of the worst in China,population based HIV interventions,including two population-wide HIV screening,have been carried out since 2005 at two townships in a remote mountainous region of Liangshan.The objective of our mathematical modeling study is to assess the temporal dynamics of the HIV epidemic in the two townships based on the data collected in the study area during the period 2005e2010.Methods:A mathematical model was set up to describe the population dynamics of HIV transmission in study area.The model was calibrated by fitting it to the HIV testing and treatment data from 2005 to 2008.Validation of the model was done by comparing its predicted value of HIV prevalence in 2010 to the prevalence data obtained in the 2010 population wide HIV testing.The validated model was used to produce estimation of HIV incidence,prevalence and death.Results:Our model estimations show that population-based HIV interventions have significantly slowed down the rise of the HIV epidemic in the two townships.Over the five-year period from 2005 to 2010,the year-over-year rate of increase in HIV incidence,prevalence,and death has declined by 91.5%,28.7%,and 52.3%,respectively.Conclusion:Mathematical models,when integrated with epidemiological and surveillance data,can be an effective tool for predicting the temporal dynamics of HIV and assessing the impacts of HIV interventions. | Zhimin Su Caiting Dong Ping Li Hongxia Deng Yuhan Gong Shiyong Zhong Min Wu Yuhua Ruan Guangming Qin Wen Yang Yiming Shao Michael Li | 2016 | Infectious Disease Modelling2016，1，1： | 2 |
