天柱山旅游环境承载力研究

研究构建了旅游环境承载力模型，对天柱山旅游环境承载力进行了定量分析，并采用问卷调查方法进行了深入探讨。研究表明，天柱山具有良好的旅游环境承载力本底值，风景区尚未大片开发，空间环境容量与实际接待游客量之间尚有很大的空间，基础设施容量突显制约性作用，提出了提高环境承载力的对策与建议，为天柱山旅游可持续发展提供了理论依据。     

中国地学第一歌——《中国地质学会会歌》

“大哉我中华!东水西山,南石北土真足夸。泰山五台国基固,震旦水陆已萌芽。古生一代沧桑久,矿岩化石富如沙。降及中生代,构造更增加；生物留迹广,湖泊相屡差。地文远溯第三纪,猿人又放文明花。锤子起处发现到,共同研讨乐无涯。大哉我中华!大哉我中华!”     

Investigation of the effects of humic acid and H2O2 on the photocatalytic degradation of atrazine assisted by microwave

A solution of atrazine in a TiO₂ suspension, an endocrine disruptor in natural water, was tentatively treated by microwave-assisted photocatalytic technique. The effects of mannitol, oxygen, humic acid, and hydrogen dioxide on the photodegradation rate were explored. The results could be deduced as follows: the photocatalytic degradation of atrazine fits the pseudo-first-order kinetic well with k = 0.0328 s⁻¹, and ·OH was identified as the dominant reactant. Photodegradation of atrazine was hindered in the presence of humic acid, and the retardation effect increased as the concentration of humic acid increased. H₂O₂ displayed a significant negative influence on atrazine photocatalysis efficiency. Based on intermediates identified with gas chromatography-mass spectrometry (GC-MS) and Liquid chromatography-mass spectrometry (LC-MS/MS) techniques, the main degradation routes of atrazine are proposed.     

Phytoplankton community from Lake Taihu, China, has dissimilar responses to inorganic and organic nutrients

To evaluate the response of phytoplankton from Lake Taihu to di erent types of nutrients, the phytoplankton responses were measured after adding inorganic nitrogen (N) and phosphorus (P) or decomposed algal scum (Microcystis spp.) into the lake water. Both types of nutrients promoted an increase in phytoplankton biomass as determined by chlorophyll a and algal wet weight. The addition of decomposed algal scum resulted in a significantly greater phytoplankton response than the addition of inorganic N and P alone. The dissolved inorganic N and P in the inorganic nutrient treatment were found not limit phytoplankton growth. The higher algal biomass obtained in the treatment with decomposed algal scum indicated the importance of other organic nutrients besides N and P such as trace elements, as well as the importance of the form of N since the levels of ammonia nitrogen (NH4 +-N) from the decomposed algal treatment were actually higher than that of the inorganic N and P addition. Microcystis spp. (Cyanobacteria), Scenedesmus spp. (Chlorophyta) and Synechocystis spp. (Cyanobacteria) were the dominant taxa in the control, inorganic N and P treatment, and the decomposed algal scum treatment, respectively. Microcystis never bloomed in response to both types of nutrient additions indicating that the bloom propagation is not solely related to nutrient additions, but may be related to the absence of selective grazing from zooplankton.

珠江口和大鹏湾海豚体内石油烃含量

为了积累海豚污染基础资料,保护海洋濒危动物,本文用荧光分光光度法测定了珠江口及其附近海域5头海豚(3个种)体内的总石油烃(TPHs)含量。结果表明,不同组织中TPHs含量与脂肪多少显著正相关(r=0.746~0.989,P0.02),在腹部皮肤和额隆中占优势,在肝脏、心脏、肾脏、肌肉中比在肺、肠和胃组织中略高。海豚TPHs含量为鱼类、虾类的2.2~3.2倍,海豚脂肪可将海水中的石油烃浓缩103~104倍。
