In this study, we present a detailed inter-annual analysis of four remotely sensed leaf area index (LAI) products: GLASS, GLOBALBNU, GLOBMAP, and MODIS LAI, and conduct correlation analysis between LAI and three meteorological variables over China. The results manifest that the four products agree well in most of northern regions of China, with higher correlation coefficient and the same response...
Land use and land cover change (LULCC) can influence regional climate by altering the surface roughness, soil moisture, and heat flux partition. LULCC information therefore is important for providing a better understanding of land-atmosphere interaction. A key requirement for such data for use in climate studies is the generation of land use maps on at least an annual basis. However, current continuous...
The consecutive growth in China's grain output over the past decade has partly depended on the expansion in grain sown area. The paper examines spatiotemporal patterns of China's grain sown area by using a complete decomposition approach. The results show that changing grain sown area during 1978–2012 is the product of augmenting multiple cropping index (MCI), shrinking share of grain crops and loss...
Accurate evaluation and prediction of the potential impact of climate change on crop production is essential to the sustainable development of a country's agriculture. Model variations plus uncertainties in the future climate change scenarios create a big challenge for such evaluation. In this work, we developed a statistical crop model using the historical yield data between 1981–2010 from the National...
It is unusual inadequate precipitation that is the main factor leading to agriculture drought. The degree of precipitation deficit, the occurrence frequency and the duration are the main aspects for the quantitative calculation of drought hazard. China is a vast country with the complex and various types of landforms, and is affected by the significant monsoon climate, as result the farming activities...
Mountain areas provide essential ecosystem services and are water towers for people living in downstream. The paper elaborates the specific vulnerability contexts and situation of mountain people and their social-ecological systems, highlights the importance of mountain ecosystem goods and services for China's sustainable development. The basic requirements of ecological modernization in China's sustainable...
As the population of China becomes more urbanized, cities will continue to expand, unknowingly igniting the multi-dimensional vulnerability of human settlements. Sustainable urban settlement requires serious manifestation in the form of low-carbon city construction. The growing urbanization trend, especially in mountain areas and in coastal areas, makes the search for policy solutions acute. Climate...
Aerosols directly impact radiance balance of the earth by scattering and absorbing solar radiation, it remain as one of the major uncertain factors in estimating radiative forcing. The spatial and temporal characteristics of aerosol optical depth (AOD) were measured by CE-318 sun-photometer. Angstrom wavelength exponent (a) and the aerosol turbidity coefficient (P) were retrievaled in Shanghai and...
China is a beautiful country with hundreds of thousands of mountains spreading over the country. Climate change poses a potentially major challenge to social and economic development in China mountain areas. Development is successful if it reduces the vulnerability of mountain areas and poor people to existing climate variability, while also building in the potential to anticipate and react to further...
In recent years, the environment has deteriorated and the sandstorm has been serious around Beijing regions, so monitoring vegetation change in Beijing and Tianjin sandstorm source control area is very important. The vegetation change of Beijing and Tianjin sandstorm source control area in 2008 was studied using MOD13Q1 NDVI data. The results have shown that the low coverage vegetation mainly grew...
Frequent adverse weather and other emergencies in recent years challenge emergency management capabilities of logistics industry in China. The weakness in emergency management of our country's logistics industry not only caused huge losses of their own, but also seriously affected downstream industries of the supply chain as well as society and livelihood. On the basis of the analysis of present conditions...
Carbon diplomacy is a brand new field in contemporary international relation arena. The United States emphasizes carbon diplomacy positively and has issued a series of related policies, which China can use for important reference. Referencing American experience, China should strengthen the ecological environment protection in carbon diplomacy, striving for international recognition, actively seeking...
Climate change and low-carbon development problems are one of the most important issues which have composite meanings and long-term influence in current international system. In face of the urgent energy and environmental problem, the low-carbon diplomacy on behalf of reducing the greenhouse gases international negotiation has gradually become the crucial part of the superpowers' diplomatic relations...
With the global "low-carbon economy" booming, energy conservation and emission reduction on tourism is a focus of global concern, because tourism is the important sector of carbon emission. Many tourism regions have proposed the measurements of energy conservation and emission reduction. Research on tourism emission reduction also began to rise. However, energy conservation and emission...
The paper selects China and Canada as samples respectively on behalf of developing countries and developed countries, according to the data from “the BP World Energy Statistics 2009” and the formula about carbon emissions from calculation handbook which in the UN's Intergovernmental Panel on Climate Change (IPCC) in 2006, the amount of total carbon emissions, per capita carbon emissions and carbon...
Glass curtain wall atrium can provide the building with good lighting and sight-seeing, but since thermal property of glass is unstable, interior environment usually alters with the climate, air condition system is required to reach the comfortable level of body. Hangzhou is taken as a typical example in subtropical monsoon climate region to certificate the limitation of glass atrium use in the south...
In recent years, the runoff of Haihe River basin has decreased significantly, especially after 1980s, due to climate change and human activities. So in this paper, a variable fuzzy method was adopted to research the variation characteristics of rainfall and runoff, and infer the main driving factors for runoff reduction. According to the parameter of the theorem and its relationship with zero, the...
Based on the observation of the thunderstorm days at ten weather stations in the area of Linyi, the characteristics of temporal and spatial distribution of thunderstorm days from 1962 to 2009 has been analyzed. The results indicate that the thunderstorm days are varied in different regions of the area, but the differences are small. The thunderstorm days decreased significantly by 3.4 days for every...
Climate change policy and position drives the transition to a low carbon economy, creating opportunities and risks to which businesses must respond to succeed.This paper presents the key policy drivers by sector and summarise the international policy shaping China position. It studies provide in depth analysis of key issues to inform businesses and policy makers on how to address climate change and...
Based on reference literature, this paper use DEA Malmquist technology to establish the total factor index model considered the variable returns to scale for evaluating carbon emissions performance and analyzed the results. And then, based on the STIRPAT equation, the paper used provincial panel data to test the main factors of carbon emissions performance in China. All the results showed that: In...
