关于长江产业带建设总体布局的初步思考

重点开发长江是90年代中国经济重大战略布署。将长江产业带建设成具有强大经济实力的国家一级经济轴线,宜采用分层次推进与中心辐射相结合的发展战略,以浦东开发和三峡建设为契机,加强基础产业,发展新兴产业和第三产业,优化产业结构,以能源和交通建设先行,改善基础设施。同时,要协调产业带建设与浦东开发、三峡工程建设的关系。     

Effect of Mountain Relief and Industrial Air Pollution on Biometric Characteristics of Pine Stands

The effect of mountain relief and industrial air pollution on biometric parameters of pine stands was studied. The empirical–statistical models of the dependence of biometric characteristics on the parameters of forest sites were developed using raster modeling and multivariate analysis. The possibility of predicting changes in the biometric parameters at any site on the basis of these models is shown.     

The implications of new information and communication technologies for sustainability

This paper discusses the relationship of new information and communication technologies (ICTs) and sustainable development. It deconstructs popular myths about a sustainable information society. One myth is that telework has reduced the need to travel and hence environmental pollution. The reality is that teleworkers make up only a small share of the total workforce, telework can generate new social relationships and hence the need for more travelling, work-related travel produces only a small amount of the total carbon dioxide emissions, and that the total distance travelled per employee is constantly rising. Another myth is that information economy is weightless and dematerialized which reduces environmental impacts. The energy and resource intensities of the ICT sector are indeed lower than the one of the total economy. The ICT sector also emits less CO₂ than the total economy. But the ICT sector constitutes only a small portion of the total value added and fossil fuel combustion is still the dominant activity of modern industrial economies. Some stakeholders argue that virtual products allow resource, energy, and transport savings. But burning digital music on compact discs and DVDs, printing digital articles and books, etc. results in rebound effects that cause new material and energy impacts, computers have a low life span of 2–3 years, reusable and upgradeable computers and computer equipment are hardly used and might not be as profitable as non-reusable ones, computers are consuming much energy. Alternatives such as energy consumption labels on ICTs and green ICTs that consume less energy contradict dominant economic interests. A sustainable information society is a society that makes use of ICTs and knowledge for fostering a good life for all human beings of current and future generations by strengthening biological diversity, technological usability, economic wealth for all, political participation of all, and cultural wisdom. Achieving a sustainable information society costs, it demands a conscious reduction of profits by not investing in the future of capital, but the future of humans, society, and nature.     

搞好生态建设,转移农村剩余劳动力

大量闲置劳动力会造成巨大生态压力,加剧生态退化,但只要转移消化得当,便能化为强大的力量和优势。本文从区域→行业→企业→家庭→生态建设联合体五个层次和角度,对各种有效的和有可能的转移消化闲置劳动力生态建设途径进行了探索。     

新时代国土整治与生态修复转型思考

针对全球变化影响下的国土空间和生态系统,生态文明建设和国土空间规划是中国在新时代的积极响应,国土整治与生态修复的转型和提升成为必然要求。在介绍国土整治与生态修复概念内涵的基础上,指出中国国土空间生态环境问题的复杂性和生态文明建设的新理念要求决定了国土整治与生态修复的转型。从工作理念、理论基础、技术体系和制度建设等方面,分析了当前国土整治与生态修复工作中存在的不足,主要包括整体综合理念滞后、理论基础体系欠缺、技术支撑相对薄弱、体制机制不尽完善等方面。针对这些不足,提出了新时代国土整治与生态修复转型的路径和策略,主要策略包括强化系统思维、提升理论体系、加强技术支撑、完善机制建设等内容,以期为国土整治与生态修复推进美丽中国建设提供科学依据。     

成都市施工扬尘排放特征研究

采用DustTRAK TM气溶胶（粉尘）监测仪对成都市112个不同类别的房建、市政工地施工扬尘进行测试,研究了不同类别施工扬尘的排放特征,分析了下风向扬尘浓度的变化趋势,并采用CALPUFF对成都市新都区某建筑工地的排放进行了模拟.结果表明：（1）成都市施工扬尘排放浓度约为0.13~2.91mg/m³,其中房建类施工平均浓度约为0.94mg/m³,高于市政施工;大型工地扬尘平均浓度约为0.61mg/m³,低于中型和小型工地;土方施工阶段平均浓度约为1.21mg/m³,远高于地基建设、主体建设、装饰阶段.（2）成都市施工扬尘呈现出高低浓度交替的周期性变化,其中房建工程土方施工阶段的高低浓度差值可达到0.6mg/m³以上.（3）施工扬尘在场界外下风向5~15m范围内会出现浓度增加的趋势,随后逐渐下降,在50m附近逐渐趋于稳定,稳定浓度介于0.1~0.2mg/m³.（4）CALPUFF模型能较好地从宏观角度来模拟成都地区施工扬尘的扩散趋势,但难以捕捉施工扬尘在下风向近距离的扩散特征.     

中国化学品环境暴露评估领域的综合区划

大尺度空间（中国）化学品环境暴露多介质模型的建立需要先对空间做相应的区划.本文以ArcGIS软件为平台,通过有空间约束的聚类方法和水文分析方法相耦合,建立全国范围的综合分区.全国范围分为华南综合大区、华北综合大区、西北综合大区、华东综合大区、东北综合大区和西南综合大区6个综合大区.每个综合大区又分别包含了若干个综合小区,小区总数为38个.该研究为我国暴露评估的综合分区提供了一个方案,在多介质模型的建立中起着重要的作用.     

略谈淮北市城市景观生态建设

为了保护淮北市城市生态环境，拟利用城市景观生态学原理对该市城市景观进行生态设计，包括城市自然组分、非自然组分设计。自然组分包括种群源、廊道、节点等内容，力争使自然组分成为环境质量的控制性组分，使城市生态良性循环、物种多样并持续存在和流动可达，物质循环、能量流动、信息传递畅通。
