沿海滩涂的“零净损失”法律制度研究

“零净损失”法律制度发端于美国,是美国为了保护其湿地而设立的一项制度。这一制度已经得到世界上不少国家的采纳,其实施有效保护了湿地。沿海滩涂作为湿地的重要组成部分,具有非常重要的生态功能,需要进行“零净损失”的保护,而且其所具有的动态性也使得这一制度在我国具有可行性。沿海滩涂的“零净损失”法律制度不仅包括面积的零净损失,也包括生态环境质量的零净损失。因而其法律制度是一个系统的内容。     

Restoring complex vegetation in urban settings: The case of tidal freshwater marshes

Tidal freshwater marshes have diverse plant communities that vary spatially and temporally due to hydrology, animal activity, and other factors. Development of urban centers along rivers of the U.S. Atlantic coast has reduced the historic extent and quality of these and other coastal wetlands. Because the vegetation of these wetlands is more complex than that of salt and brackish marshes (where restoration of vegetation typical of natural systems has sometimes been successful), restoration of tidal freshwater marsh vegetation is likely to be more difficult, particularly in urban areas. Watershed urbanization alters hydrology, sediment load, propagule availability and composition, nutrient status, and other variables that together create an environment different from that of wetlands in less developed areas, possibly precluding restoration of typical marsh vegetation. Tidal freshwater wetlands were historically extensive along the Anacostia River in Washington, DC, but most of these were lost due to filling, dredging, or hydrologic alteration. Over the last decade, the U.S. Army Corps of Engineers has implemented projects designed to restore tidal freshwater wetlands along the Anacostia, which involved increasing elevation with dredged river sediment and planting native vegetation. To illustrate some of the mechanisms affecting vegetation development in restored tidal freshwater marshes in urban areas, I present a case study on one of these wetlands, Kingman Marsh, that also includes research at another restored wetland and two natural reference sites. Studies by my research groups indicate that the restored wetlands undergo essentially a planting-modified process of primary succession. Low densities of seeds are initially present in the substrate, and prolific seed dispersal into the restored sites results in high initial plant diversity comprised of plantings and ruderal (i.e. weedy) natives and exotics. Seed banks develop rapidly at the restored sites, probably due to colonization and early reproduction by ruderal species. Hydrology and disturbance by non-native animals (including resident Canada goose) are important variables controlling establishment of vegetation in these systems. Recent literature and the case study indicate that the environmental conditions of urban settings impose constraints in restored wetlands that result in plant communities more like those of urban natural wetlands than those of wetlands in less urbanized watersheds. This suggests that rather than design wetland restoration projects with the goal of creating pristine wetland vegetation, restorationists must identify, accept, and if possible capitalize on the ecological constraints of the urban environment in setting achievable and desirable restoration goals.

灿烂的传统潮文化

中国古代发达的海洋文化中,潮文化占有较大比重,且历史悠久。古代潮文化中,"潮"词含义广泛,并非仅指周期潮汐,还指非周期的潮灾。潮灾主要是风暴潮,但也包括海啸(津浪)。周期性潮汐包括普通的潮汐和暴涨潮(涌潮),而普通的潮汐又包括"天文潮"与"地理潮"。此外,除了潮汐,还包括大海中的"潮流"。在古代,潮文化对沿海资源开发、农业、减灾、航海、战争、科学技术、文学艺术、生活习俗、旅游、宗教、哲学等方面均有广泛而深刻的影响。     

神本主义人性观和扁平人物——兼分析奥康纳《好人难寻》中的人物

美国女作家弗兰纳里.奥康纳作品中的人物形象引入注意,在奥康纳所塑造的人物群像中鲜有正面形象,而奥康纳对笔下人物所表现的冷漠和其中所反映的反人本主义的人性观念,曾招致广泛的误读。应该把奥康纳的创作主旨纳入对其人物分析的研究视野之内。奥康纳是一名虔诚的基督徒,基督教观念对她的文学创作具有一种根本的规定性。在基督教神本主义人性观的视角下,神性启示是言说人性的一个基本前提,奥康纳文学作品中的人物并不具有自足价值。以奥康纳的代表作《好人难寻》为例,在对其中的人物进行叙述学分析的基础之上得出结论:该作品中的人物为扁平形象。扁平人物的塑造是奥康纳对基督教神本主义人性观的文学表达。

利用物理光学法推导出在双站情况下，平面波以任意角度入射时，导体平板的散射矩阵公式。通过该公式分析在特殊角度入射情况下散射场的雷达散射截面（ＲＣＳ），并与文献解进行比较，验证了它的正确性。该公式结构清晰，计算简便，有利于进一步分析散射场的特性。     

沿海滩涂产权的复杂性及其解决方式

沿海滩涂是由潮上带、潮间带和潮下带滩涂三部分组成的处于海洋和陆地交汇处的资源,因其既有陆地资源的属性,又兼具海洋资源的特性,决定了其在产权属性上既有土地产权的特征,也有海洋产权的特性。然而在现实中,因为滩涂概念界定不清晰、产权残缺、征用滩涂引起的产权变化等因素导致滩涂占有和使用混乱,为此必须通过清晰的滩涂概念界定、完善各项制度并实现各种制度之间的协调来完善沿海滩涂的产权制度。
