利川市生活垃圾卫生填埋场场址的比选

选址是卫生填埋场建设和运行的关键。以利川市实际情况为前提和依据，筐选出7个预选场址，经实地踏勘和从填坦容量、运输距离、搬迁户数量等方面分析，遴选出其中3个；分别从工程学、环境学、经济学、社会与法律等方面中如交通状况、服务年限、占地面积、基岩类型、渗透系数、地下水位、覆盖土来源等13项具体条件上对3个备选场址进行了详细的分析比较，确定杨柳村大天井为最终选定场址。利川垃圾填埋场的选址工作也可以为同类型的城市或地区提供参考和借鉴。     

Sustainable resource management coupled to resilient germplasm to provide new intensive cereal–grain–legume–livestock systems in the dry savanna

Sustainable resource management is the critical agricultural research and development challenge in sub-Saharan Africa. The accumulated knowledge on soil management gathered over the last 10 years, combined with solid crop improvement and plant health research at farmers’ level, has brought us to a stage where we can now address with confidence the intensification of cereal–grain–legume-based cropping systems in the dry savanna of West Africa in a sustainable and environmentally positive manner.Two sustainable farming systems that greatly enhance the productivity and sustainability of integrated livestock systems have been developed and implemented in the dry savanna of Nigeria. These are: (i) maize (Zea mays L.)–promiscuous soybean [Glycine max (L.) Merr.] rotations that combine high nitrogen fixation and the ability to kill large numbers of Striga hermonthica seeds in the soil; and (ii) miflet [Eleusine coracana (L.) Gaerth] and dual-purpose cowpea [Vigna unguiculata (L.) Walp.]. Improvement of the cropping systems in the dry savanna has been driven by the adoption of promiscuously nodulating soybean varieties (in particular TGx 1448-2E) and dual-purpose cowpea. The rate of adoption is very high, even in the absence of an efficient seed distribution system. The number of farmers cultivating the improved varieties increased by 228% during the last 3 years. Increased production of promiscuous soybean has been stimulated by increased demand from industries and home utilization. Production in Nigeria was estimated at 405,000 t in 1999 compared to less than 60,000 t in 1984. Economic analysis of these systems shows already an increase of 50–70% in the gross incomes of adopting farmers compared to those still following the current practices, mainly continuous maize cultivation. Furthermore, increases in legume areas of 10% in Nigeria (about 30,000 ha in the northern Guinea savanna) and increases of 20% in yield have translated into additional fixed nitrogen valued annually at US$ 44 million. This reflects, at the same time, an equivalent increase in land-use productivity, and with further spread of the improved crops, there are excellent prospects for additional economic and environmental benefits from a very large recommendation domain across West Africa.     

深圳生态市建设规划框架研究

开展生态市建设规划是加强我国城市生态环境管理和促进城市可持续发展的重要工作。与国内其它城市相比,深圳市具有雄厚的经济基础、较高的环保意识和优越的地理位置等优势。结合深圳生态市建设规划,提出建设国际化、高水平、精品生态市的规划目标并分解到初级、中级和高级三个规划建设阶段,在此基础上研究制定生态深圳“五个三”规划研究体系和规划思路以及21项重点研究内容,以此作为生态深圳建设规划研究框架。
