基于相对资源承载力的可持续发展问题研究——以河北省为例 总被引:1,自引:0,他引:1
采用相对资源承载力的研究思路与计算方法,分别计算出1996—2005年河北省土地资源、经济资源的相对承载力和综合承载力,并分析了其动态变化过程。研究表明:①河北省综合承载力一直处于超载状态,经济资源承载力于2004年后呈现富余状态,经济资源成为河北省的主要承载资源;②与环渤海的其它4省市相比,相对土地资源承载力处于富余状态,相对经济资源承载力处于超载状态;③河北省内11个地市相对资源承载力存在着地区差异。通过河北省相对承载力方面的研究,提出了河北省实现可持续发展的对策与建议。 相似文献

农村养老体系的有效建立,离不开农村最重要的土地资源,如何利用农村土地来优化农村养老体系,提升养老质量,就显得尤为重要。针对这一课题,笔者通过河北省农村基层建设年活动,对河北省不同县市的10个村500个农户进行了调查,查找农村土地流转和农村养老面临的问题和困境,并针对当前农村养老体系不健全,新旧养老保障模式衔接不畅和农村土地流转水平低下、流转形式单一的现状,提出农村土地制度的改革要为农村养老提供资金支持,要为新旧农村养老保障体系的转变提供便利的宏观建议。 相似文献

The Axios River delta and the Inner Thermaikos Gulf coastal zone have experienced a long period of human interventions during
the past 100 years. A post-evaluation of long run coastal zone changes under the Drivers-Pressures-State-Impacts-Response
(DPSIR) conceptual framework is presented. The DPSIR approach is then used to project out into possible futures in order to
connect with policy and management options proposed for the improvement of the current conditions and the achievement of sustainable
development, in the coastal zone. Socio-economic driving forces with their origins in the end of the 19th century have generated numerous pressures in the coastal environment that changed the state of the environment. In the first
part of the last century, there was no coupling between change of state and policy. Due to increasing environmental awareness,
a coupling became more apparent over the last thirty years. Human interventions include river route realignment, extensive
drainage of the plains, irrigation network, roads and dam constructions. The consequences were positive for the economic development
of the area, human health, and navigation for the port of Thessaloniki. In contrast, the manipulation and over-use of natural
resources has led to a reduction of wetlands, biodiversity loss, stress on freshwater supplies, and subsidence of coastal
areas, aquifer salinization, and rapid coastal erosion. Three plausible future scenarios are utilised in order to investigate
the implications of this environmental change process and possible socio-economic consequences. 相似文献

Bangladesh, situated on the delta of the Ganges, the Brahmaputra, and the Meghna rivers, experiences two distinct types of inundations: (a) river floods resulting from excessive runoff contributed by monsoon precipitation and (b) coastal floods induced by storm surges of tropical cyclones. The river floods are normal annual events and human settlements and agricultural practices have adapted admirably well to their regimes. Abnormal floods that occur once in every few years cause serious damage to crops and properties. To minimize flood losses, a number of modern engineering projects have been constructed within Bangladesh. However, the successful solution of the problem would probably require some international collaboration for basinwide unified systems planning, since large parts of the drainage basins of Bangladesh lie beyond its borders. In the absence of such collaboration, internal resources should be utilized for the construction of smaller public projects, such aspolders, and for encouraging and reinforcing various types of indigenous adjustments to floods. There are very few successful indigenous adjustments to coastal floods. Most of the structural solutions, such as community shelters and higher embankments, are expensive public projects that are probably beyond the means of the internal resources of the country. 相似文献

Spatial and Temporal Effects of Port Facilities Expansion on the Surface Area of Shallow Coral Reefs
There is a close relationship between ports and reef areas, mainly because reefs provide protection to vessels against extreme weather events like storms and hurricanes. This historical relationship has generated severe impacts on reef ecosystems. In order to identify the main impacts from the construction of port facilities in shallow coral reef areas, we analyzed and described the effects of land reclamation and coastal structure construction associated to port growth throughout a century in the Sistema Arrecifal Veracruzano National Park, Mexico. We used aerial photographs and maps of the nineteenth and early twentieth century to assess the impacts caused by port expansion activities on shallow coral reefs. Three types of impacts were identified: (a) direct reef area loss caused by landfills and perpendicular coastal structures construction leading to the loss of nearly 50 % of the fringing reef near to the port; (b) fragmentation in short- and medium-term scale, which affects two fringing reefs, and (c) long-term modification of coastal dynamics leading to sedimentation and loss of a complete reef area. On the eve of a new expansion of Veracruz Port, we used the New Port Project Plan, long-shore net drift geomorphic indicators and the port impact typology from the 100-year period assessment to evaluate a possible future scenario. The scenario describes how the new expansion project will repeat the three types of impacts affecting a whole reef area, which is currently part of the National Park. 相似文献

Summary In Queensland, Australia, instream resources planning ranges from "fragmentary" to overlooked. But the State of Queensland, with engineer dominant water management, is only a little behind some other Australian States and Western countries in evaluating the environmental uses and values of river systems. Management is pragmatic about its abundant water endowment! Highly contrasting biophysical environments, from arid to tropical rainforest, as well as a dominance of ephemeral river systems should not preclude instream assessment. The new coastal $A430 million, Burdekin Falls Dam, the "1800's dream" has radically altered that river and delta region for economically amorphous agricultural purposes and, seemingly, to encourage crocodiles to recreate. In comparison, the "urbanised" Brisbane River is the focus of southern state water use competition issues such as flooding, eutrophication, turbidity, public access, preservation of river islands, sand and gravel mining, and recreation. A veritable host of river related management authorities preside!Dr Diana Day is trained as a fluvial geomorphologist and a water policy analyst. Her research has focused on natural resources management especially related to water and soil/land assets. Dr Day is an editor of the newAustralian Journal of Soil and Water Conservation. Her many publications include a recent book entitledWater and Coal -Industry, Environment and Institutions in the Hunter Valley, N.S.W., published by The Australian National University, Canberra, where until recently she was a Research Fellow. Dr Day is currently a Water Planner in the public sector. 相似文献
