区域工业发展与碳排放的脱钩关系分析——基于2006~2013年湖南的实际情况

根据湖南省“十一五”以来（2006~2013年）的工业发展和碳排放情况，分析湖南工业发展与碳排放之间的脱钩弹性、节能弹性、减排弹性，结果表明：湖南工业行业发展的过程中，较好地控制了碳排放量，但节能减排任务依然较大。因此，新常态下应以“节能、减排”为主线，深入优化产业结构，调整能源消费结构，从而确保工业可持续发展的同时，实现碳排放的合理控制。     

河北省塞罕坝机械林场改革发展调研报告

塞罕坝机械林场建场52年来完成了4项历史任务,为京津地区筑起了一道绿色生态屏障,成为京津重要生态区。林场通过内部体制改革,引入竞争机制,实行场长任期目标管理责任制,全面推行绩效工资制度、目标承诺制度和领导包保森林防火风险抵押金制度,着力培育新的产业经济增长点,各项事业健康发展,生态建设取得辉煌成就。但林场发展面临定位不清、体制不顺、生产生活等基础设施相对滞后、社会保障制度不健全等问题。对策:从根本上解决体制问题,明确定位,分类经营,完善社会保障,促进林场稳定与发展。     

Summer drought decreases Leymus chinensis productivity through constraining the bud,tiller and shoot production

Extreme drought events can directly decrease productivity in perennial grasslands. However, for rhizomatous perennial grasses it remains unknown how drought events influence the belowground bud bank which determines future productivity. Ninety‐day‐long drought events imposed on Leymus chinensis, a rhizomatous perennial grass, caused a 41% decrease in the aboveground biomass and a 28% decrease in belowground biomass. Aboveground biomass decreased due to decrease in both the parent and the daughter shoot biomass. The decreases in daughter shoot biomass were due to reductions in both the shoot number and each individual shoot weight. Most importantly, drought decreased the bud bank density by 56%. In addition, drought induced a bud allocation change that decreased by 41% the proportion of buds that developed into shoots and a 41% increase in the buds that developed into rhizomes. Above results were supported by our field experiment with watering treatments. Thus, a 90‐day‐long summer drought event decreases not only current productivity but also future productivity, because the drought reduces the absolute bud number. However, plasticity in plant development does partly compensate for this reduction in bud number by increasing bud development into rhizomes, which increases the relative allocation of buds into future shoots, at the cost of a decrease in current shoots.     

Puerarin improved growth performance and postmortem meat quality by regulating lipid metabolism of cattle under hot environment

This study aims to evaluate the effect of puerarin on performance, meat quality, and serum indexes of beef cattle under hot environment. Thirty-two bulls were divided into four groups and fed diet supplemented with puerarin at 0, 200, 400, or 800 mg/kg. Results showed that heat stress was employed for 54 out of 60 days, 400 mg/kg group declined serum cortisol (COR) contents, all treatments increased the contents of total cholesterol, high density lipoprotein cholesterol, and total superoxide dismutase activity; in addition, glutathione peroxidase activity of 200 mg/kg group were enhanced, only 800 mg/kg group enhanced immunoglobulin (IgA, IgM, and IgG) and low density lipoprotein cholesterol contents compared with the control (p < .05). Moreover, 400-mg/kg puerarin increased serum growth hormone levels compared with 200 mg/kg group but declined COR concentrations compared with 200 mg/kg and 800 mg/kg groups (p < .05). More importantly, average daily gain and daily matter intake, and intramuscular fat contents of 400 mg/kg group were enhanced, but the shear force of beef in 400 mg/kg and 800 mg/kg groups were declined compared with the control (p < .05). These findings indicated that supplemental with puerarin enhanced immune and antioxidant, and 400 mg/kg of puerarin improved performance and meat quality by normalizing levels of stress hormones and increasing intramuscular fat deposition of beef cattle under hot environment.
