基于GIS实现的中国土壤侵蚀背景数据库若干技术问题

建立准确可靠、精确可用的中国土壤侵蚀背景数据库是进行全国或区域范围内土壤侵蚀定量评价及土壤侵蚀时空特征研究的基础工作,也是其重要的手段和途径。就小比例尺全国土壤侵蚀背景数据库的建立过程,探讨了该类数据库在ARC/INFO软件系统上实现的技术方法,以及数据精确程度的控制问题。

Building capacity for integrated coastal management in developing countries

The need for building human and institutional capacity has been identified in Agenda 21 of the UNCED conference as well as by a number of international environmental institutions as essential for integrated coastal management (ICM) and sustainable development in developing coastal states. There is a growing need for coastal management practitioners and organizations with expertise in planning and implementation for ICM. The application of strategies for institutional development and building human capacity in coastal management and other fields shows that short-term intensive training efforts and long-term institutional strengthening programs are appropriate to address the issues and needs of ICM. An overview of the experience of the URI/USAID International Coastal Resources Management Program in Sri Lanka, Thailand and Ecuador presents lessons learned for strengthening ICM efforts in developing countries.
