基于InVEST模型和最小成本路径的城市绿色空间生境网络构建方法研究——以南京为例

提出以城市绿色空间为载体,选取不同生境类型、对城市化适应能力不同的物种为目标物种,结合物种观测数据和InVEST模型生境质量评估模块进行生境源地的识别及成本面信息的提取,应用最小成本路径综合模拟出城市绿色空间生境网络的方法。以南京为例,选取了9种鸟类作为目标物种,分析了其现状城市绿色空间网络结构。结果表明,迁移能力和城市化适应能力对物种分布的范围和生境类型的广泛程度影响较大。现状网络对城市化适应能力强或迁移能力强的物种较友好,对城市化适应能力差且迁移能力弱的物种有严重不良影响。对于综合的网络,中部的核心区多但被建设区割裂,北部的核心区少而分散,南部的核心区少但联系紧密,三部分的主要连通性结构为滁河、溧水河、秦淮河、秦淮新河和较连续的山林地或水库坑塘。此外,在半自然生境斑块内也生成了许多分散路径,部分联系紧密的斑块形成了组团结构。最后,根据以上结果提出了相应建议。

Green Tourism in Mountain Regions-Reducing Vulnerability and Promoting People and Place Centric Development in the Himalayas

In recent years, mountain regions are attracting great attention to Indian tourists in general and foreign tourists in particular. The potential mountain resources for promoting green tourism are enormous in the form of natural and cultural heritage such as biosphere reserves, flora and fauna, lakes and rivers and traditional rural resources. In order to utilise tourism industry market, uncontrolled numbers of tourists and related haphazard infrastructural facilities in the vulnerable mountain regions pose serious environmental implications. The ecological pressures are threatening land, water and wild life resources through direct and indirect environmental impacts together with generation of solid and liquid wastes, so green tourism is emerging as an important task in order to develop new relationship between communities, government agencies and private sectors. The strategy focuses on ecological understanding, environmental protection and ecodevelopment. The major attributes of the green tourism include environmental conservation and education and distribution of income to local people based on strong partnership. Various knowledge systems go a long way for achieving the goals of the green tourism, which creates awareness about the value of environmental resources. Mountains have ecological, recreational, educational and scientific values, which need to be utilised in sustainable way. Various tourist activities and facilities need to be diversified in order to achieve multiple benefits including scientific field excursion, recreation in natural and cultural areas, community festivals and sport tourisms. Green tourism considers tourism development as an integral part of a national and regional development. The paper discusses the social, economic and environmental dimensions of the green tourism with particular reference to village tourism development programme taking empirical evidences from the Himalaya. Such programme also minimises biophysical and human vulnerability and risks in mountain regions. The environmental consciousness campaign and introduction of code through multi- purpose Tourist Resource Centres are gaining currency in above context.

Industrial transformation and green production to reduce environmental emissions: Taking cement industry as a case

Industrial transformation and green production(ITGP) is a new 10-year international research initiative proposed by the Chinese National Committee for Future Earth. It is also an important theme for adapting and responding to global environmental change. Aiming at a thorough examination of the implementation of ITGP in China, this paper presents its objectives, its three major areas, and their progress so far. It also identifies the key elements of its management and proposes new perspectives on managing green transformation. For instance, we introduce a case study on cement industry that shows the positive policy effects of reducing backward production capacity on PCDD/Fs emissions. Finally,to develop different transformation scenarios for a green future, we propose four strategies: 1) policy integration for promoting green industry, 2)system innovation and a multidisciplinary approach, 3) collaborative governance with all potential stakeholders, and 4) managing uncertainty,risks, and long-time horizons.

Green technical innovation, environmental expenditure, and the environmental Kuznets curve:a dynamics model

The relationship between the emission of pollutant and economic growth has attracted a lot of attention in the environmental debate of the recent decades. Based on some theoretical and empirical research on environmental Kuznets curve （EKC）, this paper introduces the environmental technical innovation and environmental investment into Salow growth model to discuss the relationship between GDP per capital and the emission of pollutant By the dynamic simulation and parameters analysis, the results of the model indicate： （1） when ＂green＂ technical progress and environmental investment are fixed, the relationship between GDP per capital and the emission shows the linear relationship; （2） ＂green＂ technical progress can lead to the positive growth rates with a decreasing level of emission, which is compatible with an EKC; （3） the proportion of the environmental investment can lead the different growth rates and level of emission. These results can explain that developing countries are ＂too poor to be green＂.

Measuring the Effect of Foreign Direct Investment on CO2 Emissions in Laos

This paper aims to explore the determinants of C〇2 emissions in Laos by accounting for the significant role played by foreign direct investment(FDI)in influencing C 02 emissions during the period 1990-2017.We apply a Johansen co-integration testing approach to investigate the presence of co-integration,and the empirical findings underscore the presence of a long-run co-integration relationship between CO2 emissions,FDI,per capita GDP,and industrial structure.We also employ an error-correcting model to examine the short-term dynamic effect of FDI on CO2 emissions.The empirical results show that FDI has a significant short-term dynamic effect on changes in CO2 emissions,indicating that the relationship between FDI and CO2 emissions is an inverted U-shaped curve.This is a validation of the EKC.Changes of FDI,per capita GDP,and industrial structure increase CO2 emissions.Based on the analysis results,this paper puts forward policy suggestions emphasizing the need for both Laotian policymakers and Chinese investors to improve eco-environmental quality.
