Restorating marine coastal ecosystem health as a new goad for integrated catchment management in Tolo Harbour,Hong kong,China
收藏 引用
Chinese Journal of Population,Resources and Environment 2004年 第2期2卷 11-19页
作者: lam k.C. Department of Geography and Resoure management The Chinese University of Hong Kong.ShatinNew TerritoriesHong KongChinahe paper demonstrates why it is necessary to take the restoration of marine coastal ecosystem health as a new goal for integrated catchment management in coastal area of the Tolo Harbour. The present goal of integrated catchment management (ICM) in the Tolo Harbour is to meet with Water Quality Objectives. The performance of an ICM plan Tolo Harbour Action Plan (THAP) is evaluated by using marine coastal ecosystem health indicators including stress indicators and responses indicators. Since the implementation of THAP in 1988 some significant reduction in pollution loading has been observed - reduction of 83 % of BOD load and 82 % of TN between 1988 and 1999. There has been an improvement in the health state of Tolo Harbour marine coastal ecosystem as evidenced in the trends of the physical chemical and biological indicators although some reverse fluctuations in some periods exist. However this can only be considered as the first sign of the ecosystem health restoration since ecosystem health covers not only physical chemical and biological aspects of an ecosystem but also ecosystem-service-function aspect. It is recommended to take the restoration and protection of marine coastal ecosystem health as a new goal instead of water quality objective management for integrated catchment management in Tolo Harbour catchment. Steps to further improve the marine coastal ecosystem health of Tolo harbour are discussed in the paper.
The paper demonstrates why it is necessary to take the restoration of marine coastal ecosystem health as a new goal for integrated catchment management, in coastal area of the Tolo Harbour. The present goal of integra... 详细信息
