安徽省工业固体废物管理现状、问题与对策

本文根据历年统计资料对安徽省固体废物管理现状进行了分析，认为该省固体废物管理具有如下特点：(1)工业固体废物产生量总体上存在着上升趋势，并将随着经济发展继续增加；(2)固废综合利用率逐步提高；(3)虽然近年来工业固体废物排放量大幅下降，但污染隐患依然存在。本文还探讨了当前该省工业固废管理存在的问题，提出了加强工业固废管理的对策建议。     

甘肃永登雹云回波群体特性分析

本文用711测雨雷达实测的冰雹云过程回波资料,分析了大小回波在雹暴形成中的演变过程以及回波强度和回波高度间的关系.结果表明永登防雹试验区回波覆盖面积比最大频数时为3.64%,平均为7%,回波块数最大频数为6块,平均为6块;回波覆盖面积比与雹日的月际变化呈正相关,回波块数与雹日的月际变化呈负相关;回波厚度在识别雹云中有重要意义.     

Perceiving Land-Degrading Activities from the Lay Perspective in Northern China

Investigation into local peoples’ perceptions can produce useful information that could be incorporated into the decision-making process to help resolve environmental problems. Within the arena of land degradation, a number of studies have also been conducted to explore local peoples’ views of the problem. However, the perceptions of land-degrading practices of the general public have so far not been actively solicited. This study aimed to contribute to this area of research by adopting the psychometric scaling technique to empirically explore the lay public’s ecological risk perceptions of land-degrading activities in Minqin County in Gansu Province, northern China. The primary data were collected via a questionnaire survey (n = 1,138) administered between 14 and 31 December 2002. The major findings of the survey were: (1) Respondents perceived the ecological risks posed by different land-degrading activities to be different. (2) There was a considerable incongruence in the way in which mining of groundwater was conceived by experts and laymen, respectively. (3) Respondents were pretty unsure of expert knowledge. (4) Respondents’ ecological risk perceptions were significantly affected by their personal attributes. As far as the policy implications of these findings are concerned, this study accentuates that we must be aware of, and involved in, the environmental perceptions of the lay public in order to succeed in guiding any human-environment tensions along more sustainable trajectories and navigating the transition to sustainability.     

吉林省城市干旱缺水风险评价体系与模型研究

以吉林省地级城市为研究对象,从造成城市干旱缺水的致灾因子危险性,承灾体的暴露性、脆弱性和防旱抗旱能力四个方面着手,利用自然灾害指数法、加权综合评价法和层次分析法,建立了城市干旱缺水风险评价模型,引用城市干旱缺水风险指数(UDRI),对城市干旱缺水风险程度进行了评价,并借助GIS技术绘制了吉林省城市干旱缺水风险分布图,以期为实现吉林省水资源可持续利用、保障区域经济可持续发展和老工业基地改造战略实施提供科学依据.

走特色旅游之路,兴江西旅游经济——兼谈大力发展江西省地学旅游

2001年8月，江西省提出了发展全省经济的战略思想-“三个基地，一个后花园”。其中“后花园”就是指把江西省建设成为沿海发达地区游客旅游观光的好去处。但我国幅员辽阔，新奇奥妙的风光比比皆是，已有26个省份先后提出将旅游业作为优先发展的支柱产业，如果拿不出自己的特色旅游产品，就很难在日趋激烈的竞争旅游市场上将旅游资源优势转变为经济优势，作者以江西省地学旅游为例，对发展江西省特色旅游的可持续性，实施战略，意义等方面进行了较少深入的探讨，以期对江西省实现旅游大省的目标起到抛砖引玉的作用。

Alternating nitrification-denitrification via nitrite for nitrogen removal from soybean wastewater by SBR with real-time control

A novel treating technology for nitrogen removal from soybean wastewater was studied. The process for nitrogen removal was achieved by alternating aeration and mixing, combined with real\|time control strategies. Results showed that the COD and total nitrogen removal rates are more than 90% and 92% at COD and total nitrogen loads of 1.0-1.2 kg COD/(kgMLSS·d) and 0.20-0.27 kg TN/(kgMLSS·d), respectively. In addition, it could improve sludge settling property. SVI value is less than 70 g/ml during the whole cycles. The method not only may be adapted to treat soybean wastewater with high nitrogen, but also may be applied to treat other high nitrogen wastewater.
