Effects of environmental factors on the production and release of matrix-bound phosphine from lake sediments

Effects of pH, temperature, and oxygen on the production and release of phosphine in eutrophic lake sediments were investigated under laboratory tests. Results indicated that the elimination of matrix-bound phosphine was accelerated under initial pH 1 or 12. Phosphine levels could reach maximum under initial pH 10. The contents of phosphine increased with the addition of alkali under pH 4–12. The rates of phosphine production and release from lake sediments varied with temperature. 20°C was the most favorable temperature for the production of matrix-bound phosphine. Oxygen showed little effect on matrix-bound phosphine. Matrix-bound phosphine concentrations in lake sediments were concluded to be dependent on a balance of natural generation and depletion processes.

滇池湖滨区新农村建设中的污染防治工程技术方案研究

对滇池湖滨区农村环境现状及主要环境问题进行了详细分析，就工程总体思路、设计原则及主要考核指标体系等进行了探讨，提出沿湖农村非点源污染防治工程技术方案，即通过以沼气池为纽带的农村能源结构改造、村级污水处置处理和配套沟渠系统建设、村内垃圾处理处置以及普及卫生旱厕、村庄道路修缮及绿化等工程和管理措施，从源头上控制污染物产生量，减少入湖污染负荷，有效地解决滇池环湖新农村建设中的环境保护问题。     

云南湖区公众环境宣传教育活动浅析

湖泊综合治理,单靠行政手段和经济手段是远远不够的,必须发动群众,依靠湖区周边的广大群众,通过广泛深入地进行环境保护宣传教育,提高广大群众的环境保护意识,促使他们自觉自愿地投身于湖泊的治理和建设中去,湖泊治理才能取得预期效果.     

自然条件下石羊河终闾湖泊模拟研究

石羊河流域史前曾存在大面积的终闾湖泊---猪野泽。自西汉开拓河西以后的两千多年以来,受人类活动影响,石羊河流域土地覆盖发生了显著的变化。灌溉农田取代了天然绿洲,而且面积逐步扩大,农业用水急剧增加,猪野泽逐渐退缩成许多小湖,并于近代干涸。在假设人类活动（主要是灌溉）对水资源未加利用的条件下（理想状态）,通过确定流域的水量收支和改进水量平衡模型,对石羊河流域现代自然条件下“终闾湖”的面积进行了模拟重建,得出现代终闾湖的面积至少应为５８０ｋｍ^２。     

武汉城市湖泊环境地球化学研究--以东湖为例

选择武汉市具有代表性的城市湖泊——东湖，进行湖泊底积物及湖水的环境地球化学研究，主要研究了湖水电导率(Ec)的变化趋势和湖泊底积物中重金属Cu、Pb、Zn、Cd、Hg等元素含量的变化规律，最后得出：武汉东湖已经开始受到重金属污染，重金属污染是人类活动直接影响的后果。

杞麓湖主要污染物的动态变化特征研究

以１９９７年杞麓湖水质监测结果为基础，运用相关分析，双因子方差分析等方法，对杞麓湖主要污染物动态变化特征的研究结果表明，杞麓湖主要污染物的空间分布较为均匀；ＢＯＤ５和ＴＮ都有较为明显的季节变化。     

抚仙湖水环境地理信息系统的设计

以抚仙湖水环境地理信息系统为例,论述了GIS技术在水环境保护方面的具体应用,着重对系统的总体设计、系统的功能模块、系统的数据库设计以及系统建立的技术策略进行了详细的描述与论证。说明了利用GIS技术对湖泊环境管理工作带来的巨大便利。系统的建立对保护抚仙湖湖区环境,促进沿湖周边县市乃至整个云南省的经济发展都具有重要的现实意义。     

Present status and changes of the phytoplankton community after invasion of Neosalanx taihuensis since 1982 in a deep oligotrophic plateau lake, Lake Fuxian in the subtropical China

Phytoplankton assemblages in the subtrophical oligotrophic Lake Fuxian, the second deepest lake in China, were investigated monthly from September 2002 to August 2003. A total of 113 species belonging to seven phyla were identified, among them, a filamentous green alga, Mougeotia sp., dominated almost throughout the study period and comprised most of the total phytoplankton biomass.Mougeotia sp. has made a substantial development during the past decades: it was absent in 1957, only occasionally present in 1983,increased substantially in 1993, and became predominant in 2002--2003. It is likely that natural invasion of the Taihu Lake noodlefish (Neosalanx taihuensis) has led to a change of dominant herbivorous zooplankton from small to large calanoid, which has increased grazing pressure on small edible algae, and thus has indirectly favored the development of the inedible filamentous Mougeotia sp.
