修订后的《中华人民共和国刑法》增加了“破坏环境资源保护罪”。对“破坏环境资源保护罪”的设立、认定以及刑事处罚等方面进行了分析，分析其对保护环境的作用以及存在的不足之处。     

林丹(γ-六六六)在土壤中的吸附性与其在土壤和小麦中残留量的关系

本文利用~(14)C—林丹研究了γ-六六六在不同土壤中的吸附性及其在土壤和小麦中残留量的关系。试验表明,γ-六六六在土壤中的吸附率与土壤中的有机质含量、可萃取铝含量和酸性等均有密切关系。同时,环境温度对吸附率也有一定影响。通过~(14)C—林丹在不同土壤和小麦植株中残留量的测定,证明土壤中γ-六六六的吸附率、小麦对土壤中r-六六六的吸收率以及γ-六六六在土壤和小麦中的残留量相互之间均有明显的相关性。为此,本研究不仅摸清了某些影响土壤吸附γ-六六六和小麦吸收γ-六六六的理化因子,同时,对用土壤某些理化性质的测定值来预测栽培试验时土壤和小麦中六六六的残留水平提供了一个途径。     

消油剂乳化率检验中标准曲线的选择

本文经过比实验，详细研究了添加双象１号消油剂对原油标线的影响，并对乳化率检验中的两种标准曲线进行了统计检验。结果表明：不添加消油剂制作的原油标线可使乳化率结果降低１￣３％左右，甚至个别消油剂的乳化率结果可相差２０％左右，两条标线的统计差异非常显著。所以制作标准曲线时必须按比例添加消测剂才能确保执法数据的可靠性。     

总有机碳测定仪的新用途──测气体中CO_2的研究

用ＴＯＣ总有机碳测定仪来鉴定污水和生活用水处理效果及污染指标是它的一项实际应用，而本义介绍的用来测定ＣＯ２则是一项开创性的工作。作者在对进口的ＴＯＣ仪使用的基础上研究了测定气体中总碳、总有机碳尤其是ＣＯ２问题，取得了较好的结果并应用到实际测定中。     

云南省经济增长与能源消耗的计量模型研究

根据云南省1985~2003年能源消耗的统计数据以及人均GDP统计数据,分析人均GDP与能源消耗之间的相关关系,选取相关性较好的能耗指标(煤炭消耗量、石油消耗量、天然气消耗量、电力消耗量)建立两者之间的计量模型。并在此基础上分析能源消耗与人均GDP增长的关系。经研究发现,云南省经济增长与能源消耗呈类似于EKC的倒U型曲线,且曲线尚未到达转折点,能源消耗量随着经济增长将持续增长。有必要采取有利措施倡导“循环经济”、“绿色GDP”等使曲线走势向良性方向发展。     

A Simulation of Temporal and Spatial Variations in Carbon at Landscape Level: A Case Study for Lake Abitibi Model Forest in Ontario,Canada

Using a case study of the Lake Abitibi Model Forest (LAMF), this study aims to assess the temporal and spatial variability in carbon storage during 1990–2000, and to present a comprehensive estimation of the carbon budget for LAMF's ecosystems. As well, it provided the information needed by local forest managers to develop ecological and carbon-based indicators and monitor the sustainability of forest ecosystems. Temporal and spatial carbon dynamics were simulated at the landscape level using ecosystem model TRIPLEX1.0 and Geographical Information System (GIS). The simulated net primary productivity (NPP) and carbon storage in forest biomass and soil were compared with field data and results from other studies for Canada's boreal forests. The results show that simulated NPP ranged from 3.26 to 3.34 tC ha⁻¹ yr⁻¹ in the 1990s and was consistent with the range measured during the Boreal Ecosystem-Atmosphere Studies (BOREAS) in central Canada. Modeled NPP was also compared with the estimation from remote sensing data. The density of total above-and belowground biomass was 125.3, 111.8, and 106.5 tC ha⁻¹ for black spruce, trembling aspen, and jack pine in the LAMF ecosystem, respectively. The total carbon density of forested land was estimated at 154.4 tC ha⁻¹ with the proportion of 4:6 for total biomass and soil. The analysis of net carbon balance of ecosystem suggested that the LAMF forest ecosystem was acting as a carbon sink with an allowable harvest in the 1990s.     

在纺织品生产中推行生命周期评价

随着社会的进步和全民环境意识的提高，人们对纺织品的健康安全要求也越来越高。在此，结合纺织品生产和加工的四个阶段，包括纺织原料生产阶段、纺纱织造阶段、印染加工阶段及纺织品后整理阶段存在的化学品残留、噪声、废水、废气等环境问题，论述了在纺织服装生产中开展生命周期评价的重要意义。     

云天化粉煤灰的综合评价及利用建议

以云天化集团有限公司自备电厂为例,在该厂所排粉煤灰理化性能测试数据的基础上,进行了质量综合评价,并对其综合利用提出了初步建议:利用三、四电场的粉煤灰可作水泥活性混合材、制备低标号(≤325号)水泥和压浆材料I一、二电场的粉煤灰则可作混凝土和砂浆的掺和料、农用磁化肥等。通过努力,将云天化粉煤灰100％综合利用,并获良好的经济效益是完全可能的。     

Vegetation patterns and nature reserve construction in an extremely-arid desert in Anxi,NW China's Gansu Province

Anxi County is located in the northwestern part of the Hexi Corridor in gansu Province and has the sole national level nature reserve of extremely-arid desert in China.Phytosociological methods (Braun-Blanquet,1964) are used to classify plant community types in this area.Eleven are disting uished,including six of deserts,four of oases and one transitional type between deserts and oases.Direct gradient analysis (DCA) is employed to correlate the distribution of plant communities to physiogeographic conditions.This study makes clear that water is the most important ecological factor for the distribution of plant species and communities in this area.The effects of water have been demonstrated in different ways.A vegetation gradient from lower altitude to higher altitude in the southern part of the reserve is driven by a precipitation gradient.The effects of the depth of ground water table contribute to the differentiation of vegetation from desert to oasis in the flat area.In a finer scale,the washed gullies have obviously higher species richness and also higher vegetation cover than the surround gobi surfaces,possibly caused by the effects of floods.The vegetation patterns demonstrate that the area of Anxi County is a complete landscape unit.The range of the current nature reserve is not large enough for the purpose of conserving the unique biodiversity in this area.
