A Deliberation in Design Standard for Energy Efficiency of Buildings in Hot Summer and Cold Winter Zone

A contradiction existed in "Design Standard for Energy Efficiency of Residential Buildings in Hot Summer and Cold Winter Zone(JGJ-134-2001)" is pointed out through calculations and the contradiction is perfectly solved by means of interrelation principle between window and wall.At the same time the constant form principle of equal thermal resistance in parallel connection between window and wall is advanced to make the controlling indexes for enclosure in buildings satisfy perfectly the requirement for energy efficiency.     

Local adjustment method for field experiments. 2. Application in experiments with and without replications

Summary Presented are the results of an application of the local adjustment Field-method in the analysis of the real field experiments without replications and in experiments with pseudo- and random replications. It was found that the local adjustment allowed a more precise estimation of the real values of genotypes in all kinds of experiments over a wide interval of spatial heterogeneity. The results obtained indicate that by simply using up to 5 random replications the decrease of the spatial effects is inadequate for fields with medium and high soil heterogeneity or with unsuccessful randomization. The Field-method which has sufficient precision in evaluating spatial heterogeneity, considerably increases the reliability of estimates in experiments even with a small number of replications or with unsuccessful randomization. Therefore, for all field experiments that have fulfilled the necessary requirements the Field-method is recommended as an obligatory statistical procedure for a prior data analysis as it allows an accurate estimation of the real character expression of genotypes, as well as the random variance in experiments without replication and the parameters of ANOVA in ones with pseudo- and random replications.     

温度对锯谷盗成虫水平和垂直运动分布的影响

为明确不同温度条件下锯谷盗成虫的水平和垂直运动规律,设置不同温度观察了锯谷盗成虫在无粮和铺有小麦水平面上的爬行速度,以及其在垂直小麦粮柱内的移动速度和分布情况.结果表明:锯谷盗成虫在水平方向上的爬行起始温度为12℃,此后随温度的升高爬行速度加快,其中在无粮平面上的爬行速度与温度的回归方程为y=13.09x-18.79,在铺有小麦平面上的爬行速度与温度的回归方程为y=3.939x-5.307,且在无粮平面上的爬行速度显著快于铺有小麦的平面.锯谷盗成虫的垂直移动也与温度相关,温度低于11℃时少有垂直移动.温度大于15℃后垂直移动速随温度升高而加快.在等温小麦粮柱内,锯谷盗成虫向上运动的速度明显大于向下移动速度.在有温差的粮柱(堆)内,成虫较多地出现于温度22 ～34℃的范围内,且在温度为19 ～ 34℃时,移动速度差异不显著,温度高于37℃和低于19℃时,移动速度明显降低.     

宁夏盐池南海子湿地交错带判定及植被稳定性分析

为研究半干旱区盐碱湿地生态交错带及其植被群落多样性和稳定性,于2016年7月通过样方(1m×1m)调查法对哈巴湖自然保护区的南海子湿地进行了野外植被调查。首先通过游动分割窗技术将研究区定量划分为湿生带、交错带和旱生带3个不同生活环境地带(以下简称生境带),采用Shannon-Wiener指数、Simpson指数、Pielou均匀度指数、Margalef物种丰富度指数分析不同样线不同生境带间的植物群落多样性,采用M.Godron稳定性测定方法分析不同生境带植物群落稳定性。结果表明,1)东、西样线窗口宽度为6个样方,南、北样线窗口宽度为8个样方时交错带的边界可以被清晰地划定;2)不同样线不同生境带Shannon-Wiener多样性指数、Pielou均匀度指数和Simpson优势度指数的排列顺序均为交错带旱生带湿生带,而Margalef物种丰富度指数的排列顺序为湿生带旱生带交错带;3)湿生带植物种数最少,以耐盐碱植物为主,植被群落最稳定,旱生带次之,交错带植被种数最多,群落最不稳定。
