THE INTEGRATED CATC HMENT MANAGEMENT PLAN IN NEW ZEALAND AND THE ENLIGHTENMENT TO CHINA’S PRACTICE

China’s current catchment planning often focuses on formulating overall strategies for flood control and water resource distribution from a perspective of water conservancy. Usually, such plans are developed at large scales, covering a huge territory. However, city-scaled analyses, technical strategies, or roadmaps responding to issues of urban flooding, water pollution, etc. are less integrated into the current catchment planning; there is also an absence of comprehensive management methods for medium- or small-scaled urban water bodies. Combing with a case study on integrated catchment management plans (ICMP) for the Hamilton City, New Zealand, this paper reviews and summarizes the idea, role, objectives, key sections, and implementation of ICMPs in New Zealand, including a series of core tasks ranging from the trans-administrative catchment management mechanism, comprehensive and operational objectives and the technical system to the integration with long-term urban planning and Resource Consent requirements. In view of the status quo and major problems in China's comprehensive management of urban water systems, as well as the gaps in the existing formulation and implementation of catchment planning, especially the absence of integrated planning methods for medium- or smallscaled catchments that have a more direct and stronger relation with urban development, New Zealand’s experience in ICMP preparation and implementation reflects a paradigm significance.     

我国能源统计工作面临的问题及完善途径分析

能源统计工作虽然经过几次变革,但在有效反映能源经济现象实质,为国家宏观调控和制定能源政策等提供依据方面仍相对滞后。我国的能源统计在统计方法、统计范围、评价指标体系、统计报表和统计力量、统计数据等方面都不能适应现行低碳环保型可持续发展经济模式。可以从能源量、能源效率、能源结构的统计以及能源清洁生产和消耗的相关统计等方面加强我国能源统计的研究和管理。
