Mountain regions play an increasingly essential role in global sustainable development, and the related sustainable development issues have attracted increasing attention. There are obvious vertical spatial differentiation phenomena in both natural and socio-eeonomic fields with altitude being a key factor affecting the economic development of mountain regions. However, the exact influence of altitude is still unknown. Based on the county scale, this paper used the gravitational potential energy model to evaluate the effects of altitude on economic development in China. The results indicate that the high-altitude areas were the depression areas of county economic development, and county economic density showed a decreasing trend with the increase of altitude. County economic density respectively decreased by 0.10%, 0.04% and 0.02% with every 1% increase in altitude in 2000, 2005 and 2010. Here we demonstrate that high altitude has negative effect on county economy, although the negative effect presented a downward trend. The results also showed that increasing capital and labor investments could reduce the negative effect of high altitude on county economy. In 2010, with every 1% increase in capital and labor density, county economic density increased by 0.62% and 0.83%, respectively. The effects of altitude were the results of multidimensional factors. The fundamental approach to reduce the negative effects of high altitude is to combine the ecological environment and resources to develop characteristic industries. The construction of infrastructure should be strengthened, which can promote the occurrence of the contra-flow of people, logistics and capital, and promote the balanced development of county economy.

As an important component of China’ transportation systems, for a long time, the insufficient performance of transport in QinghaiTibet Plateau(QTP) was a bottleneck restricting the economic growth and social development in this area. Nevertheless, the implementation of the western development strategy has accelerated the preliminary construction of comprehensive transport network since 2000. Due to the large area and significant geographical heterogeneity, there is a growing need to understand the relationship between transportation and economic development based on the perspective of spatial difference. By using GIS-based raster analysis and Geographically Weighted Regression(GWR) model, we investigated the spatial-temporal distribution of highway, railway and airport accessibility, respectively, and estimated the correlation and heterogeneity between transport accessibility and the level of economic development. Results revealed that:(1) Transport accessibility in the QTP improved by 53.38% in the past 15 years, which is specifically embodied in the improvement of both highway and railway.(2) Accessibility presented prominent differentiation in the space, increasing from west to east and reducing with the rise of elevation, specifically, the best accessibility area of the highway is below 4000 m above sea level, while the area with an altitude of over 4000 m has the lowest aviation time cost.(3) In general, the long weighted average time cost to critical transport facilities posed significantly negative effect on county economic growth in QTP, more positively, the adverse effect gradually weakened over time.(4) Obvious heterogeneity exists at the influence of different transport accessibility factors on the level of economic development, reflecting both in the horizontal space and altitudinal belt. Therefore, region-specific policies should be addressed for the sustainable development of transport facilities as well as economy in the west mountain areas.

Permafrost is one of the key components of terrestrial ecosystem in cold regions. In the context of climate change, few studies have investigated resilience of social ecological system(SER) from the perspective of permafrost that restricts the hydrothermal condition of alpine grassland ecosystem. In this paper, based on the structural dynamics, we developed the numerical model for the SER in the permafrost regions of the source of Yangtze and Yellow Rivers, analyzed the spatial-temporal characteristics and sensitivity of the SER, and estimated the effect of permafrost change on the SER. The results indicate that: 1) the SER has an increasing trend, especially after 1997, which is the joint effect of precipitation, temperature, NPP and ecological conservation projects; 2) the SER shows the spatial feature of high in southeast and low in northwest,which is consistent with the variation trends of high southeast and low northwest for the precipitation, temperature and NPP, and low southeast and high northwest for the altitude; 3) the high sensitive regions of SER to the permafrost change have gradually transited from the island distribution to zonal and planar distribution since 1980, moreover, the sensitive degree has gradually reduced; relatively, the sensitivity has high value in the north and south, and low value in the south and east; 4) the thickness of permafrost active layer shows a highly negative correlation with the SER. The contribution rate of permafrost change to the SER is-4.3%, that is, once the thickness of permafrost active layer increases 1 unit, the SER would decrease 0.04 units.

The reformation of the economy system has led the f un ctional department and status of the enterprises into a variable state. Under th e condition of the market economy, the kernel of the enterprises’ functional dep artment has diverted to that of marketing decision-making, which face to market and meet with the need of consumption. Assuredly, the kernel of marketing decis ion-making is to prognosticate the future market demand of the production of en terprises accurately, so that it can ensure and realize the maximum of the enter prises’ profit increase. Using empirical research and the multi-regression technique, this paper ana lyzes the enterprises’ production demand forecast of the GMC (Global Management Challenge, held every year globally) and changes most of uncontrollable factors of demand forecast to the controllable ones of the enterprises. The method we us ed to forecast demand by using the multi-regression technique is as follows: 1. Look for the main factors which influence the demand of productions; 2. Establish the regression model; 3. Using the historical data, find the resolution of the correlative index an d do the prominent test; 4. Analyze and compare, regression, adjust parameter and optimize the regress ion model. Our method will make the forecast data closer to the actual prices of the future market requirement quantity in the production marketing decision-making of the enterprises and realize the optimizing combination and the working object w ith the minimum of the cost and the maximum of the profit. And it can ensure the realization of the equity maximum of the enterprises and increase the lifecycle of the production.

随着交通拥堵状况日益显著,整体交通安全性下降,交通事故率逐渐增大.基于提高驾驶安全性考虑,细化元胞长度,引入被广泛证明在描述车辆驾驶行为方面具有很高精度的Gipps安全距离规则,对Na Sch模型进行改进,提出一个新的基于安全距离的元胞自动机交通流模型.采用实测数据对模型进行标定和评估,进一步对模型进行数值模拟分析.模型评估结果显示,新建立的模型相对Na Sch模型精度更高.数值模拟结果表明,改进模型能够很好地表现交通流特性,再现实际交通中的自由流、同步流及拥堵流等交通现象.此外,还发现驾驶员对前车最大减速度估计过高时,会导致道路通行能力下降,而驾驶员对自身车辆最大减速度估计过高时,会在一定程度上增大道路的通行能力,但是很可能会造成不安全的驾驶行为,增加了事故率.

消费类公益诉讼中,消协所涉的原告地位、诉讼请求和胜诉利益分配是制度实施和发展的关键。宜将"消费类公益诉讼"分为共益诉讼和众益诉讼,消协不独占其中的众益诉讼,并对消协的原告资格在案件范围和情形方面适当限制。应从消费者个人的损害和消费者群体抽象的损害两方面界定"补偿性损害"的范围;消费者不能对诉讼中具有共同争点的损失(如支付的价款)请求惩罚性赔偿,但可以就人身损害部分作出相应请求。私益部分胜诉的惩罚性赔偿金宜分配于公益组织。
