Mitigation of the Impact of Tropical Cyclones in Northern Australia through Community Capacity Enhancement

Community mitigation of hazard impact requires hazard knowledge and preparedness on the part of the members of diverse and complex communities. Longitudinal research in the tropical cyclone prone north of Australia has gathered extensive datasets on community awareness, preparedness and knowledge, in order to contribute to education campaigns and mitigation strategies. Data have been used to identify issues of vulnerability to cyclones and capacity to deal with the hazard. This has been developed as a community vulnerability and capacity model that may be applied to diverse communities in order to assess levels of capability to mitigate and deal with the cyclone hazard. The model is presented here in a simplified form as its development is evolving and ongoing.     

Landscape structure and land uese on county level in northeastern Yunnan Province of China—a case study of Huize County

Taking Huize County as an example, the paper analyzed the landscape structure(landscape element structure, landscape type structure, landscape spatial structure, landscape succession structure) and the relations between landscape structure and land use. It was pointed out that the agriculture should be developed in harmony with the landscape structure in the study area.

草履虫──针杆藻群落对混合印染废水净化作用的条件实验

本文对混合印染废水的静态净化过程，进行了生物群落观察和条件实验。发现废水净化初期以大量细菌和草履虫（以 Ｐ． Ｃａｕｄａｔｕｍ为主）繁殖为特征，同时伴生着少量浮游藻类。随着净化过程的进行，细菌和草履虫数量下降，以针杆藻（以 Ｓ． ａｕｃｓ为主）为建群种的浮游藻类群落占优势。化学分析表明，净化作用与温度、光照条件及废水起始浓度有关。
