中国LULUCF碳核算与决策支持系统设计与开发

Design and Development of the Carbon Accounting and Decision Support System of LULUCF in China

为了服务于我国气候公约谈判和陆地生态系统碳循环管理,对我国已建立的观测、数据、模型和方法进行有效集成,实现对全国陆地生态系统碳平衡、LULUCF活动碳汇效应,以及各种履约对策综合影响的动态评估,基于IPCC理念和方法,以.NET和ArcG IS为平台,设计开发了中国LULUCF碳核算与决策支持系统。本文首先介绍了系统原型设计和基本结构,然后,详细叙述中国LULUCF碳核算与决策支持系统的11个主要模块的算法及功能实现,系统数据集成和管理方式,系统决策实现和对比分析。该系统采用C#语言进行开发,采用五层次结构模式,运用关系型数据库存储空间数据,实现了空间数据和属性数据一体化的无缝管理。该系统功能齐备并且具有扩展性,可以接受不同的核定方案,进行多途径、多方案、多情景的比对,能为我国第二次全国温室气体清单编制和LULUCF活动碳汇效应计量提供可靠、高效的方法,为国家参与气候公约谈判和履约提供所需要的基础数据和科学依据。

Along with society development,more and more greenhouse gases,such as carbon dioxide,methane,and nitrous oxide,were released to atmosphere by humanity.Scientific researches showed that the fact of global warming was incontrovertible,and how to contain or slow down global warming became a global hot spot of scientific research.In order to meet demands on evaluation of carbon source/sink inventories,UNFCCC invited the Intergovernmental Panel on Climate Change to develop Good Practice Guidance for Land Use,Land-Use Change and Forestry.Based on the.NET and ArcGIS technology,the Carbon Accounting and Decision Support System of LULUCF in China was developed to meet the requirements of National Negotiation under the climatic convention and management of carbon cycle in terrestrial ecosystem.The system was developed completely based on the IPCC idea and method,and it could efficiently integrated existed observation records,data,models and methods for dynamic assessments of Chinese terrestrial ecosystem carbon balance,carbon sink effects of LULUCF and implementation policies.In this article,we first introduced the design and framework of the system.Then we made a detailed description of the system functions and the managements of database.Followed,we described the process of system development and the operating procedures showed in the interface of the system with C# as the development language.Finally we summarized the innovative characteristics of the system.The Carbon Accounting and Decision System of LULUCF in China has complete functions and strong expandability,and it could accept many types of schemes for comparison.Considering the actual national condition,the system adopted native scientific achievements as possible in method,data and parameter to reduce the uncertainty of carbon list checking and ratifying.It would supply reliable and efficient method for secondary national green house gas list compilation,and scientific basis for National Negotiation under the climatic convention and the implementation of the convention.
