Contribution of Drought to Potential Crop Yield Reduction in a Wheat-Maize Rotation Region in the North China Plain

Journal of Integrative Agriculture 2014年第7期13卷 1509-1519页

With consecutive occurrences of drought disasters in China in recent years, it is important to estimate their potential impacts on regional crop production. In this study, we detect the impacts of drought on wheat and maize yield and their changes at a 0.5＆#176;＆#215;0.5＆#176; grid scale in the wheat-maize rotation planting area in the North China Plain under the A1B climate change scenario using the Decision Support System for Agrotechnology Transfer （DSSAT） model and the outputs of the regional climate modeling system-Providing Regional Climates for Impacts Studies （PRECIS）. Self-calibrating palmer drought severity index was used as drought recognition indicator. Two time slices used for the study were the baseline （1961-1990） and 40 years of 2011-2050. The results indicate that the potential planting region for double crop system of wheat-maize would expend northward. The statistic conclusions of crop simulations varied considerably between wheat and maize. In disaster-affected seasons, wheat yield would increase in the future compared with baseline yields, whereas in opposite for maize yield. Potential crop yield reductions caused by drought would be lower for wheat and higher for maize, with a similar trend found for the ratio of potential crop yield reductions for both crops. It appears that the negative impact of drought on maize was larger than that on wheat under climate change A1B scenario.

Contribution of Root Respiration to Total Soil Respiration in a Betula ermanii-Dark Coniferous Forest Ecotone of the Changbai Mountains, China

引用

Pedosphere 2005年第4期15卷 448-455页

作者： liu ying HAN Shi-jie ZHOU Yu-Mei ZHANG Jun-Hui Institute of Applied Ecology Chinese Academy of Sciences Shenyang 110016 （China）.

Total and root-severed soil respiration rates for five plots set up 50 m apart in a Betula ermanii Cham.-dark coniferous forest ecotone on a north-facing slope of the Changbai Mountains, China, were measured to evaluate the seasonal variations of soil respiration, to assess the effect of soil temperature and water content on soil respiration, and to estimate the relative contributions of root respiration to the total soil respiration. PVC cylinders in each of 5 forest types of a B. ermanii-dark coniferous forest ecotone were used to measure soil respirations both inside and outside of the cylinders. The contribution of roots to the total soil respiration rates ranged from 12.5% to 54.6%. The mean contribution of roots for the different plots varied with the season, increasing from 32.5% on June 26 to 36.6% on August 3 and to 41.8% on October 14. In addition, there existed a significant (P < 0.01) logarithmic relationship between total soil respiration rate and soil temperature at 5 cm soil depth. Also, a similar trend was observed for the soil respiration and soil water content at the surface (0-5 cm) during the same period of time.

Aerospace China 2006年第2期7卷 18-21页

作者： He ying,liu jie

At the beginning of 2005, the China Space Insurance Pool was appointed by Sino Satellite Communications Company Ltd. to arrange an insurance programme for the Sinosat-2 satellite. In October 2005, the China Space Insurance Pool staged a unique marketing presentation to underwriters from 19 foreign insurance companies. Also, a site tour was arranged for underwriters to view the CAST plant. During early 2006, together with the broker and the client, China Space Insurance Pool commenced the negotiations on the details of the insurance programme with the international insurance market.

Leiomyomatosis peritonealis disseminata associated with endocervicosis

引用

Chinese Medical Journal 2009年第4期122卷 474-477页

作者： liu Jian-ying ZHENG jie LIAO Song-lin Department of Pathology Health Science Center of Peking University Beijing 100191 China

Leiomyomatosis peritonealis disseminata （LPD） is a rare but well-documented disorder mainly found in young women. Occasionally, LPD coexists with endometriosis and/or multi-cystic mesothelioma. Endocervicosis is another uncommon condition, which was recognized as a distinct entity by Clement and Young in 1992 and has been documented involving the lymph node, pelvic peritoneum, bladder and small intestine. We described a case with a unique combination of LPD and endocervicosis.
