环保疏浚土资源化利用途径

针对疏浚污染土的科学处置与资源化利用，指出当前疏浚污染土利用手段的不足之处，介绍疏浚土制备回填土、免烧建材型材、绿化土等资源化利用方式，进而从3个维度即岩性特征、营养盐及重金属等污染情况、有机质及盐分含量定性与定量相结合分析疏浚污染土资源化利用途径选择的依据，并据此对太湖与白洋淀疏浚土分别成功制备免烧砖和绿化土进行实证分析。结果表明，从上述3个维度判别环保疏浚土资源化利用途径是可行有效的。     

多沙河道中的泥沙治理

为解决多沙河道中淤积泥沙资源化利用困难和生态景观差的问题，以嘎斯汰河泥沙治理为例，分析水沙过程及河床演变规律，采用梯级跌水沉沙和景观坝相结合的方法治理泥沙，能够在洪水期上拦粗沙以资源化利用，下排细沙以改善淤积形态；在非洪水期中下段实现清水满槽，提高了植物成活率，对水生态系统的构建有重要意义，并为后续工程提供借鉴。     

Adapting without Retreating: Responses to Shoreline Change on an Inlet-Associated Coastal Beach

Coastal barrier systems around the world are experiencing higher rates of flooding and shoreline erosion. Property owners on barriers have made significant financial investments in physical protections that shield their nearby properties from these hazards, constituting a type of adaptation to shoreline change. Factors that contribute to adaptation on Plum Island, a developed beach and dune system on the North Shore of Massachusetts, are investigated here. Plum Island experiences patterns of shoreline change that may be representative of many inlet-associated beaches, encompassing an equivocal and dynamically shifting mix of erosion and accretion. In the face of episodic floods and fleeting erosive events, and driven by a combination of strong northeast storms and cycles of erosion and accretion, the value of the average Plum Island residence increases by 34% for properties on the oceanfront where protection comprises a publicly constructed soft structure. Even in the face of state policies that ostensibly discourage physical protection as a means of adaptation, coastal communities face significant political and financial pressures to maintain existing protective structures or to allow contiguous groups of property owners to build new ones through collective action. These factors mitigate against adapting to shoreline change by retreating from the coast, thereby potentially increasing the adverse effects of coastal hazards.     

The Dependency of People on the Great Barrier Reef,Australia

Understanding how people are dependent on Large Scale Marine Protected Areas (LSMPAs) is important for understanding how people might be sensitive to changes that affect these seascapes. We review how resource dependency is conceptualized and propose that it be broadened to include cultural values such as pride in resource status, scientific heritage, appreciation of aesthetics, biodiversity, and lifestyle opportunities. We provide an overview of how local residents (n = 3,181 face-to-face surveys), commercial fishers (n = 210, telephone surveys), and tourism operators (n = 119 telephone surveys) are potentially dependent on the Great Barrier Reef (GBR), a region currently experiencing significant environmental, social, and economic change. We found that commercial fishers and tourism operators were dependent not only financially on the GBR, but also because of their age, years in the industry and region, lack of education, and the number of dependents. These stakeholders lacked flexibility to secure alternative employment. All stakeholder groups, regardless of economic imperatives, were dependent on the GBR because of their cultural connections. We propose that resource dependency also provides an umbrella concept to describe the cultural services provided by an ecosystem, which can be described through place-based dependence and place-identity.
