Abstract: 摘要: 碳排量的快速增加带来了严重的环境问题,并制约着经济社会的可持续发展。利用市场机制实现减排已经成为主要的碳排放控制路径。随着国内外碳市场的不断发展,国外碳期货市场必然影响国内碳现货市场的价格形成机制,进而两者的具体互动关系对于投资者理性投资和风险规避尤为重要。选取2013年12月至2017年10月之间的国际碳期货价格和国内碳价日交易数据,综合运用协整检验和Granger因果检验,在检验的基础上构建向量自回归(vector autoregression, VAR)模型,并用脉冲响应函数及方差分解法解析国际碳期货价格和国内碳价相互影响程度。研究结果表明:国际碳期货价格与国内碳价之间存在着长期的稳定关系,呈现出明显的单向因果关系;国内碳市场缺乏定价能力,因此其对国际碳期货市场影响较弱,处于被动地位。
Abstract: The rapid increase of carbon emissions has brought serious environmental problems and restricted the sustainable development of the economy and society. The use of market mechanism to achieve emission reduction has become the main control path of carbon emissions. With the continuous development of carbon market at home and abroad, foreign carbon futures market will inevitably affect the price formation mechanism of the domestic carbon spot market, and the specific interaction between them is of great importance for rational investment and risk aversion. We selected the data between December 2013 and October 2017 from the international carbon futures price and the domestic price of carbon, VAR model is constructed on the basis of cointegration and Granger causality test, and use the impulse response function and variance decomposition to analyze the mutual influence between the international carbon futures price and domestic carbon price. The results show that there is a long-term stable relationship between international carbon futures price and domestic carbon price, showing a significant one-way causality. Due to the lacks of pricing power, the domestic carbon market has a weak influence on the international carbon futures market and is in a passive position

Abstract: Man-land tensity,a value that quantitatively indicates the tension between human activity and physical environment,can be calculated by function with human pressure on the physical environment and environment carrying capacity to the human activity.A man-land tensity model is put forward in this paper through three steps.Firstly,the Environment Carrying Capacity Model(EC) is built by using the idea of Land Carrying Capacity Model and Ecological Footprint Model for reference.EC comes from the physical capacity normalized by Equivalence Factor and Yield Factor,and modified by human factors of city distribution and transport network density.Secondly,integrating production and consumption,the Human Activity Pressure Model(MP) is set up with 1 km population and GDP data.Thirdly,the Man-Land Tensity Model(MLT) is constructed based on EC and MP at 1km grid data platform.Compared with the previous research based on administrative region,1km grid is smaller on grain size and it can present the more detailed areal differentiation.The result shows that,the high-value of man-land tensity has a spot-shaped or belt-shaped distribution at cities or their suburbs or along the main economic axes,where the human activity is intense.The highest value area appears in the Pearl River Delta,the Yangtze River Delta and the Beijing-Tianjin-Hebei Metropolitan Region.The middle-value zones are distributed in North China Plain,the Two-Lake Plain(in Central China),Sichuan Basin,etc.The ecological environment is fragile in West China,where the human activity exists mainly in cities and the farming-pastoral zones,and here are distributed the high-value zones of man-land tensity.

Abstract: In recent years,many methods for fusing panchromatic and simultaneously multispectral(SM) images have been developed,however,there is little work concerning the fusion of images with significantly different spectral properties and pixel spacings though existing techniques either cannot avoid distorting their spectral characteristics or introduce artifacts.As an application of the Intensity Hue Saturation(IHS) transform and the orthogonal wavelet decomposition(OWD) in order to enhance the spatial resolution of MODIS images,intensity correlation moment model(ICMM) has been proposed based on mean and the standard deviation of both the intensity component obtained by averaging three MODIS images and the approximate component of the SPOT image decomposed with an orthogonal wavelet basis to produce one new intensity component while minimizing the degree of resampling.This system uses a self-adaptive correlation response to determine that how much the corresponding wavelet coefficients contribute to the dominant features for accurately transferring visually chromatic emergent information from any number of the input images into a single fused image.Subsequently,the high spatial resolution MODIS images are achieved through reconstructing the fused OWD coefficients by using the modulated MODIS images obtained through an inverse IHS as the approximate component and the details of the SPOT image as high frequencies.By using the ICMM as fusion rule,texture and pattern details coming from the SPOT image can be modulated to MODIS images without altering their spectral properties and contrast because fusion in the correlation response domain significantly improves the reliability of the feature selection and information fusion process.This technique can be applied to improve spatial resolution for either colour composite or individual bands.By an image fusion experiment using MODIS and SPOT images of Dapeng bay area of Shenzhen,China,the visual evaluation and statistical analysis between the original MODIS images and the fused MODIS images confirm that ICMM overcomes the preservation tradeoff and can achieve better performance in terms of both preserving spectral information and improving spatial resolution of SM images.Finally,the influence of the decomposition levels on the result is also discussed.

Abstract: In this paper,a fusion algorithm for enhancing the spatial resolution of MODIS images is proposed,based on the joint use of IHS representation and orthogonal wavelet decomposition(OWD).The basic idea consists of following steps represent the MODIS images in the IHS space,substitute the I with the high resolution intensity component obtained from the fusion with the approximate component of the SPOT image through an intensity correlation comment model based on the self-adaptively weighting(SCMM).Finally,three high-resolution MODIS images are achieved through an inverse OWD by using the three modulated MODIS images obtained by an inverse IHS transform as the approximate component and the details of the SPOT image as the high frequencies.Experiments confirm that the proposed algorithm can achieve better performance in terms of both preserving the spectral information and improving the spatial resolution of MODIS images visually and statistically.

Abstract: This paper describes factors in seed germination of Oplopanax elatus Nakai. The water permeability of seeds was good enough to support seed germination. The water extracts of the seed coat and endosperm had some germination inhibitors, and the inhibitory effect of the extracts from endosperm was stronger than that from the seed coat. The embryos were not fully differentiated (in the cardioid stage) and were in deep dormancy when seeds matured. The seeds must be stratified under warm conditions to complete differentiation and development of the embryos, then under cold conditions to complete the physiological ripeness. The development of embryos in different seeds within a seed lot were not synchronous. By changing the temperature stratification for 7 months, only a few seeds were able to germinate, but after 17 months, most of the seeds were able to germinate. Influenced by annual climate conditions, the yield and germination rate of seeds collected in different years varies greatly. The seeds can be stored for a long time; the germination ability of seeds stored for 2 years was still high.
