Dynamic macroeconomic modeling and analysis of CO_2 abatement
CO_2排放控制的动态宏观经济模拟分析

WANG Zheng,<br>
生态学报 , 2004,
Abstract: 以 Nordhaus- Pizer模型和 L eimbach模型为基础 ,在新经济增长理论框架下 ,发展了一个气候保护分析的宏观经济动态模型 ,模拟分析了不同削减水平下我国温室气体排放的对我国 GDP增长和社会福利的影响 ,数值模拟发现 :如果不推动减排 ,我国经济增长到 2 0 2 5年左右将失去优势。如果中国适当参加减排 ,采用每年控制少排放 0 .2 %的水平 ,到 2 0 5 0年相对不控制将少排放 1 0 % ,对中国经济发展最为有利 ,对全球气候保护也是一个贡献
ON THE ECOLOGICAL SENSITIVE ZONE IN CHINA

Abstract: n analysis to natural environment of China suggested that HU population line,whichlink up Tengchong and Heihe, is an important ecological boundary in China, the physical-based of the analysis are distributions of vegetable-soil system,natural disasters and climato-logical charateristics, the change of these distribution was been result to geomorphologicalregional change; in other words, the area near HU line is a ecological sensitive zone. Withphysical-geographical analysis,the sensitive zone is divided to ...
Introduction to the research of impact on economy from climate protection with modeling
气候保护及其对社会经济影响的模拟研究

Abstract: In this paper, we discussed the international research response to climate change, climate change and the economic impact of climate protection, and suggested that new research should focus on climate protection modeling and simulation. This article evaluated 6 models of the emissions scenarios used to rely on specialized report features in Fourth Assessment Report of IPCC, and pointed out the IPCC's SRES models ignore the endogenous technological progress and international GDP spillover, and attention focused on the economic effects of the passive response to climate change, so that we need to develop a proactive model now. The article also discussed the research in climate protection deficiencies in China, including reliance on foreign software and statistical models, the lack of dynamics simulation, stressed that the urgent task is to develop a new model of macroeconomic dynamics, nonlinear CGE model and simulation model based on agent, and made China-program about the global climate protection. Finally the author introduced the LRICE model framework which was developed by Wang, Wu Jing and others. The model, characterized by technological advances in learning by doing, reflects the fact that developing countries will reduce carbon dioxide emissions through technological progress, which is closer to the real world.
ON THE SYSTEM OF THEORETICAL GEOGRAPHY AND SOME QUESTIONS
理论地理学的几个问题与体系

Wang Zheng,<br>
地理研究 , 1989,
Abstract: The system of theoretical Geography is divided into 3 series in this paper. The first series is Theoretical Geography in its strict meaning, which indicates general geographical laws; the second series is Werder-meaning Theoretical Geography, which contains strict-meaning Theoretical geography and the theories of physical geography and Human geography; and the third series is Generad Theoretical Geography, which ihvolves applied theories of various, geographic things, besides theoretical geography in wider semse.The theoretical geography contains 3 branches. Regoinal Science, Geographical Environment Science and Geo-system Science. some basic concepts of these branches have been discussed in this paper.

旅游业区位分析--以云南为例

WANG Ying,WANG Zheng,<br>,
地理学报 , 2000,
Abstract: 通过对云南省旅游地分布和旅游业发展状况的分析,提出新的适合于解释旅游业的区位理论,其关键是区位的旅游轩边际效用分析模型。研究发现旅游地分布存在一种类似杜能环的旅游业区位结构,以旅游集散地为中心,由内向外,依次为“历史古迹带”、“奇异风景带”、“旅游业滞带”和“自然风光与民族风情带”的四条环带状分布。这种结构是廖什理论不能解释的,需要应用边际效用模型。
Delay-constrained and low-cost multicast routing algorithm based on key node
基于关键节点时延约束低代价组播路由算法

WANG Hui,WANG Zheng,<br> 慧, 
计算机应用研究 , 2013,
Abstract: This paper proposed a delay-contrained and low-cost multicast routing algorithm based on key node according to the construction of delay-constrained and low-cost multicast tree. This algorithm not only improved the existing path selection function which was appropriate for dynamic delay optimization, but also in conception and frequency of key node. Because key node could reduce the time complexity of choosing low-cost path in the first time to choose destination nodes. And then it used the improved path selection function to choose nodes add into the muticast tree one by one. By this way, the multicast tree which met the requirements could be constructed. The simulation results show that this algorithm can not only construct a multicast tree correctly but also need less time than those of many other multicast algorithms.
A CONNECTION WITH SPACIAL INTERACTION AND DIFFUSION
人口扩散与空间相互作用的联系

地理研究 , 1991,
Abstract: Supposing the geographical diffusion of population is Brown movement, the mechanics spacial interaction is explained to be a macro image of diffusion of population, the population is idenitcal particle which life is limited with.Where N. Number of particle, t. life time, A and B are parameters. The population-particles of two region alternate each other, it will produce a image showing potential characteristics under stable condition, a alternative force will produce because of the potential, it is spacial interaction. With this theory,we result in the spacial interaction will posses a nucleus.Where r is distance, b is a paramenter depend on the geographical process. We suggested the interactianal force followsWhere Fij. force which j point was acted by i point, Oj: Number of population-particles of j, Q1: the resoarce of i point, and a, K are parameters.

Agent- based Simulation on the Evolution of Population Geography of China during the Past 2000 Years
2000 年来中国人口地理演变的Agent 模拟分析

WU Jing,WANG Zheng,<br>吴静,
地理学报 , 2008,
Abstract: In order to simulate the evolution of population geography of China during the past 2000 years, an agent-based model is presented in this paper. In the model, population individuals are denoted as agents and geographical environment is presented by cellular automata. Agents can migrate or settle in cellular influenced by historical climatic, agricultural and social conditions which are tightly integrated with population system. With model construction, the formations of population distribution pattern in north vs. south and east vs. west are simulated, as well as the evolution of holistic population geography. Additionally, the driving forces for those population geography developments are investigated respectively. Results are as followings: 1) Even when all the climatic, agricultural and social disturbances are neglected, the correlative coefficient between the simulated population of each province and the realistic data reaches 0.9733. The result shows potential agricultural productivity makes far-reaching influence on China's population geography, determining the essential characteristic of population distribution. 2) Among the scenarios which take account of solo influence, it is found that climatic change made greatest contributions to the evolution of holistic population geography with a contribution coefficient of 0.9869. Therefore historical climate change is proved to be the main driving force for the entire evolution of population geography since 2 A.D. Further, we found that the influence of climate change is multi-phased taking the drastic climate change in 1230-1260 A.D. as a turning point. Before that climate change works faintly on population distribution, but become forceful after that. 3) Based on simulation, it is discovered that the pattern of population geography in north-south China shaped during 910 A.D.'s mainly driven by the social unrest as Anshi turmoil at that time. Because of the turmoil, millions of populations in the north move to the provinces in the south to avoid the war. 4) The pattern of population geography in east-west China is shaped during 1235-1255 A.D. Considereing the temporal social and climatic conditions, we figure the drastic climate change in 1230-1260 A.D. would be the main driving force for the formation of population distribution in east-west China.
