Contributing institutional factors of rural environmental pollution in the process of modernization in China —In the perspective of the efficiency of environmental management system

With the development of rural pollution, its characteristic and institutional factor should be studied for pollution control through economics and sociology. Based on the data gathered from investigations by several government sectors, rural environmental pollution can be divided into two types by its sources: internal source type and external source type. The internal source type is the main component of rural pollution at present, which can be further divided into three types. Research shows that the contributing institutional factors of rural pollution issues and the effectiveness of environmental management system over rural pollution can be summarized as distinctiveness. In essence, the rural pollution issue results from the dualism of rural and urban areas’ inadaptability to rural modernization. In detail, the contributing factors can be summed up on three institutional levels. There are obvious loopholes in rural environmental management system which, in the meantime, is incapable and inadaptable to rural pollution control. There exist similar questions in the related public service system, which are intensified by inappropriate reform which brought about incompatible incentive in the recent years. However, in the eleventh five-year plan period, there are advantageous trends in the three institutional levels. Main data sources in this paper: ➀ the surveys on TVEs (township and village enterprises) conducted by Township Enterprise Bureau of Ministry of Agriculture of China in 1997 and 2002; ➁ the partial survey on rural environmental conditions by EPA (environmental protection administration) of Zhejiang Province in 2002; ➂ the survey on the pollution of IPLFs (livestock and poultry farms) in 23 provinces, municipalities, and directly administered cities by the State Environmental Protection Administration of China in 2002; ➃ the research report on Mechanism of Investment and Financing for Environmental Protection by China Council for International Environment and Development Cooperation in 2003; ➄ the third investigation on national hygiene service in 2003; ➅ the regular monitoring of safe quality of agricultural products by the Ministry of Agriculture of China in 2005; ➆ the investigation arranged by the Ministry of Health which finished in 2007 and showed the total situation of rural environmental health and drinking water security of the whole country.     

1954～2008年衡阳冰冻特征及变化趋势分析

利用1954～2008年街阳8个地面气象观测站数据,对其年代际间曲线和气侯趋势系数进行综合分析,结果表明:衡阳冰冻的年代际间变化经历了上世纪70年代的活跃期,50、90年代的低谷期,目前向正常方向发展.年平均出现冰冻24.5站次,冰冻多发年的出现机率有所加大,但仍处于较低水平.1月中旬～2月上旬是冰冻相对集中时段,其中1月下旬是全年出现冰冻最多旬,而该旬并非气温最低时段.形成冰冻的有利条件是日平均气温0～-1℃,小～中等降雨(雪)过程,日平均风速5.0 m/s以下.衡阳的冰冻发生存在地域性特点,自北向南逐渐减少.轻度冰冻、中等冰冻和重度冰冻各占69.3%、25.4%和5.3%.

本文探讨和研究了活性碳吸附水中苯酚的试验方法以及活性碳对水中苯酚的吸附效率。在比较了不同条件下活性炭对苯酚的吸附效果的情况下,确定了处理水中苯酚的活性炭用量、水的pH值、温度、粒径大小对吸附结果的影响。研究结果表明,粒径<100μm,pH值为6左右的条件下,任意温度,活性炭对水中苯酚的吸附效果最好。     

Seasonal variation of Microcystis in Lake Taihu and its relationships with environmental factors

In order to monitor the changes of Microcystis along with temporal and spatial variations, seasonal variation of Microcystis in Lake Taihu was investigated by 16S-23S rRNA internal transcribed spacer denaturing gradient gel electrophoresis (16S-23S rRNA-ITS DGGE) and microscopic evaluation. Samples were collected quarterly at four sites (River Mouth, Meiliang Bay, Cross Area, and Lake Center) from August 2006 to April 2007. Results showed that Microcystis dominated total phytoplankton abundance at the four sites in all seasons except winter. The average annual abundance of Microcystis was relatively high at River Mouth and Meiliang Bay, reaching 81.22×106 and 61.32×106 cells/L, respectively. For temporal variations, Shannon-Wiener diversity index (H') according to DGGE profile revealed the richness of Microcystis in summer (H'=1.375±0.034) and winter (H'=1.650±0.032) was lower than that in spring (H'=2.078±0.031) and autumn (H'=2.365±0.032) (P<0.05). While for spatial variations, the richness of Microcystis at River Mouth (H'=2.015±0.074) was higher than at other sites during four seasons (P<0.01). Very few differences of Microcystis diversity in the same season were observed among the other three sites (P>0.05). Canonical correspondence analysis (CCA) was performed to elucidate the relationships between Microcystis operational taxonomic units (OTUs) composition and the environmental factors. Results of CCA revealed that temperature was strongly positively correlated with the first axis (r=0.963), while TSS was negative correlated with the second axis (r=-0.716). Phylogenetic tree based on the sequencing results of target bands on DGGE gel indicated that samples collected in summer and winter constituted two separated clusters.
