江浙沪地区人为NH_3排放量的估算

对１９９０年江浙沪地区人为氨排放进行了统计计算，结果表明江浙沪地区人为氨排放总量为７６９．３０ｋｔ，主要的氨来源为化肥的使用、家畜以及能源的消耗，其中家畜占３００％、化肥使用占２５０％、能源消耗占２５８％。江浙沪地区单位面积排放强度为３．６５ｔ／ｋｍ２，而人均排放量为６２６ｋｇ／人。

解决中国农村环境保护信息非对称性的方法探索

基于对世界银行项目——“中国乡镇工业企业环境行为研究”的子项目“乡镇工业企业污染控制报告制度研究”在江苏省丹阳市的实施过程的研究，发现污染控制报告会在乡镇环境管理中有着良好的社会效益、经济效益和环境效益，不失为一种解决农村环境保护信息非对称性的优选方法。     

The impacts of different kinds of dust events on PM10 pollution in northern China

In this study the frequencies of PM₁₀ (as key urban pollutant) in 14 key environmental protection cities in northern China were analyzed. It follows that the PM₁₀ concentration in the high-frequency period is higher with an extent 0.009–0.066 mg m⁻³ than in the low-frequency period of 2001–2002. Further the impacts of three kinds of dust events on the PM₁₀ concentration in four cities (Beijing, Hohhot, Xi’an and Lanzhou) were explored. The results showed that different kinds of dust events have different influences on variation of PM₁₀ concentration in these four cities. In Lanzhou and Hohhot, which are near the source areas of dust events, the contribution degree of these three dust events to the PM₁₀ is: floating dust>dust storm>blowing dust. Whereas, in Beijing and Xi’an situated in dust event passing areas, the mean value of PM₁₀ concentration is higher in blowing dust than in floating dust (no dust storm). In addition, the influences of dust events on PM₁₀ concentration are different in the cities on different dust event paths. In Beijing and Hohhot (on the northern path), the high PM₁₀ concentration is usually caused by blowing dust. But in both Lanzhou and Xi’an (on the western/northwestern path) the high PM₁₀ pollution concentration is usually caused by floating dust.

Conservation of the Northern Spotted Owl under the Northwest Forest Plan

Abstract:  Development of the Northwest Forest Plan (NWFP) was motivated by concerns about the overharvest of late-seral forests and the effects of intensive forest management on the long-term viability of the Northern Spotted Owl ( Strix occidentalis caurina ). Following several years of intense political and legal debates, the final NWFP was approved in 1994. Even though the plan evolved with a broad ecosystem perspective, it remained anchored in the Spotted Owl reserve design proposed in 1990. Based on a criterion of stable or increasing populations, a decade later it remains unclear whether the enactment of the NWFP has improved the conservation status of Spotted Owls. The results of intensive monitoring of several Spotted Owl populations for over a decade suggest a continuing range-wide decline even though rates of timber harvest have declined dramatically on federal lands. The cause of the decline is difficult to determine because the research needed to establish cause and effect relations has not been done. One plausible hypothesis is that the owl's life history greatly constrains its rate of population growth even when habitat is no longer limiting. Since enactment of the NWFP, new threats have arisen, including the movement of Barred Owls ( S. varia ) into the range of the Spotted Owl, political pressure to increase levels of timber harvest, and recent changes to forest laws that eliminate the requirement to assess the viability of wildlife populations on U.S. Department of Agriculture Forest Service lands. At this time is appears that Spotted Owl conservation rests critically on continued implementation of the protections afforded by the NWFP and the U.S. Endangered Species Act.     

江苏省部分地区农田表土多环芳烃含量比较及来源分析

采集江苏省兴化市、吴江市、宜兴市、南京市六合区的农田表层(0-15 cm)土壤样品共30个,用高效液相色谱测定土壤中16种多环芳烃(PAHs)含量.结果表明,土壤中∑PAHs含量介于45.6～2 286.8 μg·kg-1之间.兴化市、吴江市土壤中PAHs平均含量分别为1 370.3、801.1 μg·kg-1,污染严重;宜兴市、南京市六合区土壤中PAHs平均含量分别为210.8、126.7 μg·kg-1,为轻微污染或无污染.根据不同环数PAHs相对丰度和菲(Phe)/蒽(Ant)、荧蒽(Fla)/芘(Pyr)比值以及对4地的实际调查,发现调查区土壤样品中PAHs来源复杂,主要有机动车尾气排放,煤、草和木材的燃烧以及石油泄漏等.     

江苏沿海地区海洋灾害类型及其防治探讨

根据江苏沿海地区的地质地貌及气候的特点,综合分析了危害江苏沿海的海洋灾害类型,主要有海洋地质灾害、气候灾害和生物灾害等三种类型。地质灾害主要包括海岸侵蚀、海岸坍塌、和海平面上升;气候灾害主要包括台风风暴潮;生物灾害主要包括赤潮、湿地滩涂面积缩小等。提出相应的防治措施:(1)加强对海岸带地质背景和地质灾害研究,应用GIS和RS等先进技术建立海洋灾害信息系统;(2)加强海防工程建设,加高海堤提高质量,以防御灾害性海浪、风暴潮等侵袭;(3)应用生态学原理,建立沿海生态防护网,增强对风暴潮抵御能力保护沿海湿地资源;(4)加强对海洋灾害及防御知识的教育和对防灾减灾的管理等。
