基于江苏长江岸线生态修复评价指标体系,明确水土保持度中各项影响因子的计算方法。采用层次分析法分别确定水土保持度指标中各因子及评价体系中各指标的权重。补充生态指数的计算方法并明确对应的赋分等级,提出开展评价的时间节点,形成一套可用于江苏长江岸线生态修复的评价体系。以南通五山段长江岸线为例,开展该体系的应用研究。结果表明:1)2018—2020年,使用评价指标体系计算得到的生态指数逐年增大,最大增长率为90.09%。2)生态效果由修复工程建设初期的较差逐步提升为优秀。3)在已实施生态修复的岸线,应用该评价体系得到的生态效果评价与该岸线实际工程进度、生态变化情况相符,验证了江苏长江岸线生态修复评价指标体系的科学性与适用性,可推广应用于江苏其他岸线生态修复评价。  相似文献

Fishing communities, the Government of Thailand Department of Fisheries, local nongovermnental organizations, universities, the Food and Agriculture Organization of the United Nations (FAO), and FAO's Bay of Bengal Program have undertaken a partnership in management of Phang-nga Bay's coastal resources. It is the first project of its kind in Thailand, and although still in the early stages, offers insights that may contribute to our knowledge of how we can improve our management of coastal resources, including the importance of (1) building relationships within the governance process; (2) combining education, enforcement, and economic incentives to achieve compliance; (3) implementing solutions early; and (4) government support of community-based decisions. These insights reinforce trends emerging in other coastal management projects in the Asian region.  相似文献

Site-based projects were initiated in Chawka Bay-Paje, Zanzibar, and Nyali-Bamburi-Shanzu, Kenya, to demonstrate the benefits of an integrated coastal management (ICM) approach for addressing coastal issues such as tourism development and enhancement of resource-dependent village economies in eastern Africa. A two-year, multidonor project used three primary strategies to make rapid, but sustainable, progress toward ICM. These included using interagency government teams for ICM planning, adopting an internationally recognized framework for ICM as a project ''road map,'' and explicitly incorporating capacity-building strategies into all aspects of the project. Within two years, integrated ICM action strategies, prepared through participatory processes, were being implemented at both sites, and both teams were working to expand the scale and scope of ICM in their nation. More importantly, the project helped create committed, capable, interagency groups that continue to work together to address urgent ICM issues.  相似文献

在船长与引航员的法律关系上,存在一些比较流行的观点和看法,却未必经得起法律思考,缺乏一定的法律依据。将《劳动法》、《合同法》、《海商法》、《船舶引航管理规定》等法律、法规和部门的规章作为依据,从法律的角度分析船长在实际工作中遇到的问题,使船长从法律的高度正确认识船长与引航员的关系,有利于船长与引航员之间关系的认识和处理,达到驾驶台团队的和谐、驾驶台资源的充分利用,进而达到增强和改善港内引航安全,做好船舶安全管理工作的目的,同时也为了避免或减少在实践中造成行政违法行为的发生。  相似文献
