摘要：立足于城市污水可持续管理思想,利用系统科学方法,理清、分析对城市污水可持续管理的影响因素。以南京市为例,给出了不同政策组合下的城市污水管理的动态结果,并对结果进行了讨论。结果表明,要实现城市污水管理的可持续发展,必须在源头上通过政策设计(如收费)促进污水排放者参加到城市污水管理系统中,注重提高资源化和无害化能力的同时,要加强源头减量的力度。

摘要：[Objective] This study aimed to optimize the conditions for liquid culture of P. comucopiaeseeds. [Method] ＂P. cornucopiae 2＇ selected by our laboratory was used as the experimental strain in this study. Single factor experiment in conjunction with Plackett-Burman （PB） design as well as Response Surface Methodology（RSM） based on Central Composite Design （CCD） were used to screen and optimize the eight factors influencing the technique for liquid culture of P. cornucopiae seeds. [Result] Firstly, the eight factors influencing the biomass of P. cornucopiae seeds in liquid culture were confirmed by means of single factor experiment; secondly, through Plackett-Burman experiment design, three main factors influencing the biomass of P. cornucopiae seeds in liquid culture were screened, namely the amount of added mannitol, the initial pH and culture temperature; lastly, the second order model, that is Y=-70.72＋2.44X3 ＋2.67X7 ＋3.72X8 ＋0.08X3 X7 -0.01X7 X8-0.05X32- 0.34X72-0.08X82, was obtained through Central Composite Design （CCD） along with Response Surface Methodology （RSM）. [Conclusion] The optimal conditions for the production of P. cornucopiae seeds in liquid culture were as follows： the amount of added mannitol of 28.17 g/L, the initial pH controlled at 5.90, 250 ml erlenmeyer flask filled with 100 ml of liquid medium, inoculum size of 5%（v/v）, rotation speed of 150 r/min, and gyratory culture at 23.97℃ for 5 days.

摘要：采用完全随机试验设计,应用温室盆栽试验方法,研究16个月生希蒙得木实生苗在不同土壤水分条件下的生物量分配。7个希蒙得木种源参加试验,用控制浇水的方法设7个水分梯度。结果表明:在水分胁迫下,与对照相比,7个种源的希蒙得木总生物量分别下降了26.40%,37.22%,30.26%,20.11%,27.22%,30.41%,34.17%;地上部分生物量占总生物量的比例逐渐降低,地下部分生物量占总生物量的比例逐渐增加,变幅为1.64%,2.00%,2.31%,2.15%,1.85%,2.67%,2.14%;根冠比分别是对照的110.68%,147.54%,171.96%,152.36%,152.29%,226.11%,152.76%。

摘要：松干基褐腐病菌是我国重要的植物检疫性病原菌,为建立该病原菌准确、灵敏、快速的检测方法,根据该病菌与同属内形态与寄主上最接近的4个种的ITS差异区域,设计出一对特异性引物IW1、IW2,经PCR扩增,只有松干基褐腐病菌可得到约165 bp的产物,而其余作为对照的菌株均无此产物,其检测灵敏度为100 pg基因组DNA。此外,特异性引物IW1和IW2还适合于Real-timePCR,其检测灵敏度更低,为0.1 pg基因组DNA(20μL反应体系)。应用此2种方法均能成功的从人工污染了的松干基褐腐病菌的木块中检测出病原菌。

摘要：This paper studies the growth law of 23-year-old Castanopsis fissa planta- tion in Haiming forest farm （Pingguo County, Baise City, Guangxi Province） with the method of stem analysis. The results show that the average DBH, tree height and volume of the 23-year-old C. fissa plantation are 19.4 cm, 20.4 m and 0.326 1 m3 respectively. The fast growing periods of DBH, tree height and volume are the 2^nd- 8^th, 6^th-11^th, 6^th-23^nd year. Annual increment curve and average increment curve of volume haven＇t intersected in the 23 years, which means the 23-year-old C. fissais plantation has not reached the quantitative mature age. The growth equations of DBH, tree height and volume are D=1.713 3T-0.050 6T2＋0.000 7T2-1.942 2, H= 1.925 7T-0.039 8T2-2.489 0, V=-0.010 4T-0.002 4T2-4.084 8e^-0.005 T2＋0.012 7. Ac- cording to the volume regression equation of Castanopsis fissa, it will reach quanti- tative maturity in the 24~ year.
