Geomatics 与数字地球

本文论述了Geomatics的内涵及特点,强调了数字地球是真实地球的数字化再现,是信息高度富集的统一体,是当代科学技术高度发展的产物,也是人类资源共享的一种概念模式.两者包含了地球系统的相关内容,并以3S等技术为支撑.知识经济时代对地理学提出了诸多问题,人类必须从全球的角度研究一系列资源环境问题,以保证全球性可持续发展战略的实施.     

玉米深加工产业的循环经济模式研究

玉米深加工具有典型的替代能源及循环经济特征。目前玉米深加工行业面临的资源短缺和环境污染的双重制约。从促进经济与环境协调发展的角度,结合玉米深加工产业发展及环境治理现状,对玉米深加工产业的循环经济模式——玉米深加工生态产业园区建设进行了探索。通过对玉米深加工生态产业园上下游原料产业链的延伸、各环节废物的资源化分析、能源与水资源回收利用的设计和生态产业园区外围企业关系的研究,结果表明,通过实施清洁生产和延长产业链,构建闭合循环的玉米深加工生态产业链条,可实现资源、能源的有效节约和副产品、废弃物的综合利用,具有相应的环境、经济和社会效益,在增强企业绿色竞争力的同时可促进玉米深加工产业的可持续发展。该模式对吉林省及同类地区玉米深加工产业的可持续发展有指导和借鉴意义。     

1990年以来辽宁省环境与经济协调度评价

环境与经济协调发展是实现可持续发展的重要途径。关于环境与经济协调发展程度的定量评价方法和理论目前尚未成熟,从环境与经济协调发展及其协调度的概念出发,利用因子分析与相关分析相结合的方法设计了一套环境与经济协调度的定量评价方法,并对1990年以来辽宁省环境与经济协调发展状况进行了定量评价,结果表明:1990年以来辽宁省环境与经济协调状况经历了从失调向初级协调的转变过程,环境与经济协调度的发展大致呈“V”型趋势变化,“九五”时期是协调状态由失调向初级协调的过渡阶段,1997年以后环境与经济处于初级协调状态。对辽宁省环境与经济协调度的限制因子进行了分析,指出能源和水资源短缺、工业三废排放量大、局部地区生态环境问题突出、区域经济差距扩大等因素将长期制约辽宁省环境与经济协调发展。

Knowledge integration in sustainability governance through science-based actor networks

Understanding how science, technology and innovation can best help to accelerate progress in achieving sustainable development remains a grand challenge for researchers and practitioners. In the context of the global consultation process for preparing a post-2015 Sustainable Development Agenda, various science-based actor networks have emerged, aiming to translate research into political decision-making and to inform transformations towards sustainability. Over the last years, these networks seem to have taken an ever-growing role in structuring the science-policy interface in global sustainability governance. The question arises, however, how they understand and organize ‘scientific knowledge integration’ in sustainability politics.This study offers a structured comparison of twelve global science-based actor networks engaged in the implementation of the Sustainable Development Goals. It shows that these networks use two types of strategies to foster scientific knowledge integration in sustainability governance. A new framework emerges, in which each strategy corresponds to two main approaches of scientific knowledge integration: The entrepreneurial strategy generally seeks to advance advice-oriented and solution-oriented knowledge processes, while assessment-oriented and learning-oriented processes in scientific knowledge integration are mainly promoted through a mediating strategy.

An object-oriented knowledge representation structure for exploration data integration

Knowledge representation structure and reasoning processes are very important issues in the knowledge-based approach of integrating multiple spatial data sets for resource exploration. An object-oriented knowledge representation structure and corresponding reasoning processes are formulated and tested in this research on the knowledge-based approach of integrating spatial exploration data. The map-based prototype expert system developed in this study has self-contained knowledge representation structure and inference mechanisms. It is important to distinguish between lack of information and information providing negative evidence for a map-based system because the spatial distribution of data sets are uneven in most cases. Error and uncertainty estimation is also an important component of any production expert system. The uncertainty propagation mechanisms developed here work well for this type of integrated exploration problem. Evidential bellef function theory provides a natural theoretical basis for representing and integrating spatially uneven geophysical and geological information. The prototype system is tested using real mineral exploration data sets from the Snow Lake area, northern Manitoba, Canada. The test results outline the favorable exploration areas successfully and show the effectiveness of the knowledge representation structure and inference mechanisms for the knowledge-based approach.
