河道生态基流价值研究进展

分别从水资源价值、水生态环境价值与生态基流价值以及保障补偿等方面,评述了国内外河道生态基流的研究进展与存在问题。认为应将河道生态基流价值的定量计算和保障补偿作为后续研究的重点,以便为缺水地区生态基流长效保障机制的建立与枯水期有限水资源的科学管理等提供理论支撑与科学依据。     

规范河道分级管理的构想

针对我国河道等级划分、分级管理事权中存在的问题,结合党中央、国务院对河道分级管理的要求,分析我国河道分级管理的现状及存在的问题,提出了河道分级管理的总体思路,为有效协调我国行政体制"块块"管理与河道"条条"管理之间的关系,将河道管理分为流域直管、流域参管、省直管、省参管、市直管、市参管、县直管7种类型,并根据河道规范管理的需求,明确了流域机构、省水利厅、市水利局、县水利局4级河道管理机关在上述7种类型河道分级管理中的权责,为规范河道分级管理提供参考。

源头一活满河清：枣庄市峄城区推行国有河道有偿承包

1998年,山东枣庄市峄城区推行以"明晰所有权,放活使用权,用好管理权"为主要内容的有偿承包管理,在省内外引起较大反响。峄城区自1997年起便着手调查研究,并借鉴费县水利改革的成功经验,抓住源头,决定以"明晰所有权,放活使用权,用好管理权"为突破口,从改进思想、工作、管理方法入手,拓宽思路,大胆改革,推行了河道有偿承包,使责任与利益捆绑连带,创出一条"以水养水、以河养河"的国有河道管理新路子。明晰所有权,就是让干部群众知道河道国有,水利主管部门代表国家依法履行管理职能;放活使用权,就是由过去的强令制止乱毁、乱建、乱种改变为     

基于河道内流量的河流生态系统服务价值评价模型研究

为了客观有效地评价河流生态系统服务价值,高效开发利用河流水资源,基于河道内流量的特征和功能,揭示了河道内流量的生态系统服务效应;并根据河流生态系统的构成、特征、效用和功能,探讨了河流生态系统服务功能(价值)的概念和分类;最后,以河道内流量为量化指标,建立了河流生态系统服务价值评价模型,介绍了河流生态系统服务价值的价值量评价方法。研究成果以服务效应和评价模型方式揭示了河流生态系统服务价值与河道内流量之间的复杂函数关系,为河流管理部门高效开发利用和科学规划管理河流水资源提供新思路。     

河道管理问题与对策

近年来,临朐县河道存在栽植树木、种植庄稼、随意倾倒垃圾、乱打建筑物、无序偷采河沙以及未经审批建设设施等现象,严重影响了河道行洪安全。应采取河道统一规划、加大水利法规宣传力度、规范采砂秩序、加大查处违法行为等措施,确保河道防洪安全。     

长江河道疏浚砂石权属、交易与利用管理模式

分析河道疏浚工程、疏浚砂石的特点,揭示长江河道疏浚砂石的自然资源属性并未改变的本质,其处分权/出让权、收益分配权的归属与长江河道采砂权许可以及采砂收益分配的归属类似;在研究典型河道砂石交易方式及疏浚砂石利用特点的基础上,提出长江河道疏浚砂石宜采用"采砂作业+砂石出让"的交易方式,将河道疏浚施工作业与疏浚砂石资源交易的主体分开;在分析长江河道疏浚砂石利用主要环节的基础上,构建长江河道疏浚砂石利用管理模式,即河道疏浚工程与疏浚砂石交易应由政府水行政主管部门统一监管,而政府交通运输行政主管部门具体管理航道等疏浚工程,河道管理机构管理疏浚砂石出让。     

关于征收河道工程修建维护管理费的几个问题

为了贯彻落实好国家河道管理条例,进一步有计划地、系统地对河道进行整治,依法进行河道防洪工程建设,理顺河道管理条例与各有关方面的关系,提高河道抵御洪涝灾害的能力,确保经济建设的顺利进行和人民生命财产的安全,必须普遍进行河道工程修建维护管理费的征收。本文主要对河道工程修建维护管理费的征收范围、标准及征收方法等几个问题进行探讨。

Similarities and dissimilarities between the EU agricultural and rural development model and Romanian agriculture. Challenges and perspectives

The main aims of this study are to highlight the differences and the similarities between the European model of agricultural and rural development, and the state of play in the Romanian agricultural sector. Statistically speaking, the agricultural sector's indicators of the past two decades place Romania outside the family picture of the EU countries, with very slight resemblances, and very strong discrepancies between their economic, technical, and institutional characteristics. At present, competition-wise, farming and farmers in Romania are still strongly disfavoured in relation to their competitors in the old EU Member States. In Romania, the economic and institutional mechanisms have most often been devised to the disadvantage of agricultural production, by claiming that subsistence farming would be the sustainable way, and by channelling the added value to other sectors. An option to continue the agricultural policies of the past decades and to abandon the national support lent to agriculture would be particularly risky through its unpredictable and incalculable social and economic effects.     

Land use planning and health and well-being

This paper is concerned with the relationship between the planning of settlements and health. It gives a brief introduction to the issues before summarising the evidence in relation to a range of topics, concluding with some more speculative thoughts on likely future findings.Modern planning was invented in response to inhumane living conditions in 19th century cities. But in the last century the connection was lost. Only now, with concerns over climate change and obesity, is there beginning to be the realisation that the physical environment is an important determinant of health.The paper uses a particular model of this relationship based on eco-system and health determinants theories to structure the review of evidence. The review covers: lifestyle choices in relation to physical activity and diet, mental well-being and community, the local economy and income, health inequalities and strategic land use transport planning, pollution and urban form, and finally impacts on global ecology.There is now a growing consensus that while personal factors are critical in determining health, the urban environment exacerbates or mitigates health and well-being outcomes.The level of active travel (walking and cycling) and outdoor recreational activity is strongly affected by accessibility to local facilities. Access to green, natural environments, and to local social networks, are factors in mental well-being. The wider sub-regional pattern of housing, economic development, land use and transport is a determinant of social exclusion and therefore health inequalities. It also affects health-damaging pollution, adaptability in the face of climate change and the level of carbon dioxide emissions.We have literally been building unhealthy conditions into many of our towns and cities. But comparisons with the best cities in Europe indicate that it is possible to reverse the less desirable trends. Success depends, however, on more radical policies of local authority control over land and finance than any political party has yet advocated. It also requires collaboration between the full range of powerful public and private organizations that influence the built environment.Future research is likely to further strengthen these conclusions. It will become much more obvious that planning for health and well-being is not only the NHS, but about creating a health-promoting physical, social and economic environment.
