| 1 | A proposed surface resistance model for the Penman-Monteith formula to estimate evapotranspiration in a solar greenhouse显示文摘Greenhousing is a technique to bridge season gap in vegetable production and has been widely used worldwide. Calculation of water requirement of crops grown in greenhouse and determination of their irrigation schedules in arid and semi-arid regions are essential for greenhouse maintenance and have thus attracted increased attention over the past decades. The most common method used in the literature to estimate crop evapotranspiration(ET) is the Penman-Monteith(PM) formula. When applied to greenhouse, however, it often uses canopy resistance instead of surface resistance. It is understood that the surface resistance in greenhouse is the result of a combined effect of canopy restriction and soil-surface restriction to water vapor flow, and the relative dominance of one restriction over another depends on crop canopy. In this paper, we developed a surface resistance model in a way similar to two parallel resistances in an electrical circuit to account for both restrictions. Also, considering that wind speed in greenhouse is normally rather small, we compared three methods available in the literature to calculate the aerodynamic resistance, which are the r_a^1 method proposed by Perrier(1975a, b), the r_a^2 method proposed by Thom and Oliver(1977), and the r_a^3 method proposed by Zhang and Lemeu(1992). We validated the model against ET of tomatoes in a greenhouse measured from sap flow system combined with micro-lysimeter in 2015 and with weighing lysimeter in 2016. The results showed that the proposed surface resistance model improved the accuracy of the PM model, especially when the leaf area index was low and the greenhouse was being irrigated. We also found that the aerodynamic resistance calculated from the r_a^1 and r_a^3 methods is applicable to the greenhouse although the latter is slightly more accurate than the former. The proposed surface resistance model, together with the r_a^3 method for aerodynamic resistance, offers an improved approach to estimate ET in greenhouse using the PM formula. | GONG Xuewen LIU Hao SUN Jingsheng GAO Yang ZHANG Xiaoxian Shiva K JHA ZHANG Hao MA Xiaojian WANG Wanning | 2017 | Journal of Arid Land2017，9，4： | 12 |

| 3 | Effects of host, temperature and relative humidity on competitive displacement of two invasive Bemisia tabaci biotypes [Q and B]显示文摘Bemisia tabaci 在 20052008 期间从 B 遗传因子型的优势在中国出人意料地变了到 Q 遗传因子型。这观察在调查环境因素,包括的主人,温度和相对湿度(RH ) 是否能可能在遗传因子型分发解释观察移动刺激了兴趣。结果显示所有三个参数检验了影响遗传因子型 survivability。当与 Q 遗传因子型在辣椒植物上一起高耸了时, B 遗传因子型的百分比在第一和第二代在创始人人口从 66.7% 显著地减少了,到 13.6% 和 3.7% 分别地。什么时候 B (在 66.7% 点的创始人) 和 Q (在 33.3% 点的创始人) 遗传因子型独自在茄子上,或在 pepper-plus-eggplant 联合上一起被饲养, B 遗传因子型任何一个的人口尺寸仍然保持不变,或在第一和第二代有点增加了。在茄子上,在 Q 和 B 遗传因子型(3 Q 和 6 B ) 之间的竞争力上的 RH 和温度的效果不是重要的。 | Dong Chu Yun-Li Tao You-Jun Zhang Fang-Hao Wan Judith K Brown | 2012 | Insect Science2012，19，5： | 7 |
| 4 | Estimation of methane and nitrous oxide emissions from biomass waste in China:A case study in Hebei Province显示文摘Crop residue,animal manure and MSW are selected as representative biomass waste.Greenhouse gas emissions from treatment and disposal process of biomass waste in Hebei province are estimated for the period from 2002 to 2007,using the methodologies recommended by the Intergovernmental Panel on Climate Change.Greenhouse gas emission was about 10 Mt CO2-equivalent annually.About 6% of greenhouse gas emission came from open burning of crop residue,74% from management system of animal manure,and 20% from MSW disposal.Among all the greenhouse gas sources,landfill is the most concentrated one,and has significant potential of emission reduction. | LUO YuXiang1,WANG Wei1,WAN Xiao2,DENG Zhou2 & ZHU CuiPing2 1 Department of Environmental Science and Engineering,Tsinghua University,Beijing 10084,China 2 J&K China Cleaning Energy Technology Company Limited,Beijing 100085,China | 2010 | Science China(Technological Sciences)2010，53，1： | 6 |
