Determination of protection range of mining upper protective layers and its numerical simulation

Aiming at the limitation of the traditional method for determination of protection region, combined with the actual situation of a mine, a new method for determination of protection region was put forward （including the protection of working face layout and development direction）, that is, gas flow observation analysis on the spot and gas content contrast method. The protection region was determined by gas flow observation analysis, gas content contrast, and computer numerical simulation combined with engineering practice. In the process of gas content test, the fixed sampling method ＂big hole drill reaming, small orifice drill rod connected with core tube＂ was employed. The results show that the determined protection region is in accordance with the actual site situation. The fixed sampling method ensures the accuracy of gas measurement of gas content.

Effectiveness of Nature Reserves for Natural Forests Protection in Tropical Hainan: a 20 Year Analysis

The establishment of nature reserves is a key approach for biodiversity conservation worldwide. However, there is a lack of unified methodology to evaluate the effectiveness of nature reserves, particularly in China, the world′s most populous nation supporting some of the most valuable biodiversity hotspots in the world. In this study, we conducted a long-term and large-scale analysis of the effectiveness of 20 of the earliest nature reserves established in Hainan Province, an island home to among the highest concentration of plants and animals in China. Remote sensing imagery from 1988, 1998, and 2008 were analyzed to investigate the temporal and spatial changes of natural forests in these nature reserves and surrounding areas. We also conducted transition matrix analysis and principle component analysis to identify the driving factors that affect the protection effectiveness of nature reserves. The results were as follows: 1) During the 20-year period from 1988 to 2008, natural forests coverage of the 20 studied nature reserves dropped 2.34 percentage points, whereas the natural forests coverage dropped 11.31 percentage points in a 0–5 km outside reserve buffer and 9.36 percentage points in a 5–10 km outside reserve buffer, indicating a significant inhibitory effect of the nature reserves on the loss of natural forests. 2) Natural forests coverage dropped in 60% of the studied nature reserves during the 20-year period, suggesting a poor protection effectiveness of these reserves, while the coverage proportion showed some increase(0%/yr–5%/yr) in other reserves. 3) Expansion of rubber and pulp forests as part of a booming economy were the main factors affecting the effectiveness of the nature reserves for conserving natural forests in Hainan Province. The results of this study provide an important empirical basis for the protection of natural forests in Hainan Province, which can be used as a blueprint for nature reserve evaluation in other places in China.

Ice-Shielding Models for Self-Preservation of Gas Hydrates

The self-preservation of methane hydrate is a key process in its engineering applications because the hydrate can survive for a significant period under atmospheric pressure and moderate temperature. Some experiments have predicted that the shielding ice formed on the hydrate surface after initial dissociation of the hydrate plays an important role in the self-preservation effect. We propose ice-shielding models of gas hydrates to investigate the dissociation rates quantitatively, including the self-preservation process, at temperatures below the ice-melting point and at atmospheric pressure. Three general models are constructed for two temperature ranges The rate-determining process for the lower temperature range is hydrate dissociation, and those for the higher range are gas diffusion through ice or hydrate layers, which depend on the thickness of the shielding-ice layer. Our models suggest that the extent of self-preservation depends on temperature, original hydrate size, and guest substances, which can explain the experimental results.

Tunneling, overlapping owner and investor protection： Evidence from merger and acquisition in Asia

Tunneling is to describe transfer resource out of the firm for benefit of their controlling shareholders. Better legal protection and stronger social norms improve minority shareholders＇ protection from expropriation. They consequently reduce the private benefits of controlling shareholders （La Porta, 1999）. This study aims to investigate tunneling in the context merger and acquisition （M＆A） and to examine whether tunneling occurs only in emerging markets with poor law enforcement or whether it also occurs in developed countries. This study documents that managers are more likely to overpay target in merger and acquisition with high overlapped owner which have stakes in bidder and target firm. That overpayment, a transfer of wealth from owners of bidder＇s firm to overlapping owners, is a type of tunneling. This study concludes that tunneling occurs in nations not only with low investor protection, but also with high investor protection.

Regulating services in poverty ecosystems dynamics: evidences from South Asia

Valuation of ecosystem services has been sought as effective tools that enable the decision makers in designing the cost effective response policies for management of ecosystems towards alleviating the poverty especially in economically poor regions like South Asia. Various directions and linkages between poverty and degradation of ecosystem and reduced flow of ecosystem services can better be understood if the regulating services like hydrological flow and carbon sequestration by forest, and nutrient cycling and bioremediation： by wetlandv can be captured in monetary unit. South Asian Countries including India. Nepal, Pakistan and Bangladesh are the hotspots of poverty where poor depend upon various ecosystem services for their livelihoods and allocation of resource for conservation of ecosystems would have additional merit if regulating services are captured and internalized into the pubtic policy.The paperfirst raises problematic issues in valuation of regulatig ecosystem services, and attempts to link it withthe dependence of poor. Second, complexities of poverty-ecosystem dynamics are discussed. Thirdly, the possible in-tervention to achieve poverty alleviation goal is analyzed with the help of some examples from accounting and valua-tion of regulating services of lndian forest. Finally, the paper suggests that greater attention is needed to do credibleand better valuation of regulating Services so that insight from these ean be used in understanding the impact of degradation of ecosysterns On poor people.

The Future Protection and Utilization of the Marine Biological Genetic Resources beyond the National Jurisdiction--Analysis based on TRIPS Agreement

Intellectual property system gives rise to international concern in the context of development and protection of the marine biological genetic resources beyond the national jurisdiction. The core argument is whether can be current international intellectual property system plays an active role for balancing the respective benefits to make sure resolve this special area issue. The Agreement On Trade-related Aspects of Intellectual Property Right （TRIPS Agreement） provides basic requirements to international intellectual property application. This paper is intended to examine the feasibility of TR1PS clauses in the above context and then some suggestions are put forth.

Distribution of Invasive Plant Species in Relation to Environmental and Anthropogenic Factors in Five Nature Reserves in Northern China

The relationships between invasive plant species and environmental and anthropogenic factors were analyzed in five nature reserves in northern China. The distribution of invasive plants was analyzed using a Canonical Correspondence Analysis. Stepwise backward multiple regression was then done to identify the most important environmental and anthropogenic factors determining the richness and distribution of alien plants in the reserves. Total invasive plant richness varied was 25 species, 12 species, 13 species, five species and five species across the nature reserves. Invasive species richness decreased in response to environmental factors such as maximum temperature and minimum precipitation and increased in line with human activities, the total area of farmland and volume of freight. Tropical plant species declined from 31% to zero while the species originally from North America gradually increased. In respect of family composition of invasive species, most species belonged to the composites, whose proportion increased from 15%-40% from north to south across the five nature reserves while species from other families varied greatly along this gradient. Life-forms of invasive plant species varied between the reserves, but annual and perennial herbs were generally dominant. Pathways of such species were highly related to human activities and utilizations.

Modeling the distribution of Populus euphratica in the Heihe River Basin, an inland river basin in an arid region of China

Populus euphratica is a dominant tree species in riparian Tugai forests and forms a natural barrier that maintains the stability of local oases in arid inland river basins. Despite being critical information for local environmental protection and recovery, establishing the specific spatial distribution of P. euphratica has rarely been attempted via precise and reliable species distribution models in such areas. In this research, the potential geographic distribution of P. euphratica in the Heihe River Basin was simulated with MaxEnt software based on species occurrence data and 29 environmental variables. The result showed that in the Heihe River Basin, 820 km^2 of land primarily distributed along the banks of the lower reaches of the river is a suitable habitat for P. euphratica. We built other MaxEnt models based on different environmental variables and another eight models employing different mathematical algorithms based on the same 29 environmental variables to demonstrate the superiority of this method.MaxEnt based on 29 environmental variables performed the best among these models, as it precisely described the essential characteristics of the distribution of P. euphratica forest land. This study verified that MaxEnt can serve as an effective tool for species distribution in extremely arid regions with sufficient and reliable environmental variables. The results suggest that there may be a larger area of P. euphratica forest distribution in the study area and that ecological conservation and management of P.euphratica should prioritize suitable habitat. This research provides valuable insights for the conservation and management of degraded P. euphratica riparian forests.
