The simultaneous adjustment of absolute and relative measurements and the elimination of systematic error among the relative measurements have been carded out in this paper. Thus an unified temporal gravity change system with absolute reference has been established. On the basis of this, the crustal subsidence effect on gravity, which belongs to non-tectonic factor, is analyzed and the station displacement corrections are carried out, so that the long-wave disturbance is eliminated. So far our following aims are realized： the advantages of the absolute and relative measurement methods are complementary to each other; the contradiction and environment disturbance are eliminated; the amounts of information are enlarged; the sampling interval of time domain is compressed. In a word, the ability of identifying the tectonic activity process is enhanced. The results show that： there are systematic errors between the two groups of relative measurements and within the data of 10 campaigns ; the uneven local crustal subsidence in the southeast of the study area results in a linear rise of gravity value at 10 stations; they can be corrected by the regression analysis. The maps of revised temporal gravity change can obviously and integrally reflect the Ms=5.0 earthquake in Guye on October 6, 1995.展开更多

There are new changes in foreign merchants' direct investment in China,and it shifts from " green investment" featured by high risk and long period of return on investment to cross-border M&A. Since Coca-Cola failed to complete M&A of Huiyuan Juice in 2009,people have paid close attention to foreign capital M&A of domestic agribusiness. New changes and features appear in both scale and industrial areas,and M&A incidents have mushroomed in the industries of meat processing,wine,dairy and beverage,and the related industries have become the hot areas of cross-border M&A. Through the study of M&A incidents in China's agriculture-related areas in recent years,this paper aims to offer an overview of current foreign capital M&A of China's agribusiness in terms of scale and industry.展开更多

According to current situations,it analyzes significance in protecting capital farmland and significance and functions of application of 3S technology in dynamic monitoring of capital farmland. With the aid of examples,it discusses functions of remote sensing and GIS in dynamic monitoring of capital farmland. It is believed that 3S technology not only can provide accurate parcel data of capital farmland changes for reviewing land change survey,but also can provide data for monitoring development situations of capital farmland,as well as provide basic current information for decision-making department.展开更多

That need is evident in constructing a geographic or locational knowledge base that examines countries, regions and cities. This study constructs a database on the impacts of climate change using Google Scholar entries for 200 countries and capital cities. A series of maps reveal the vast unevenness in the database, especially between Global North and Global South countries. The discussion explores these sharp differences and suggests future research topics for much-needed global, interdisciplinary and international research.展开更多

Heavy financial burden on governments has been increasing as reconstruction of natural disaster and prevention of public construction spending. Unlike the climate mitigation activities, the main purpose of climate adaptation is to establish climate risk management system. We discuss several types of financing instruments and collect several cases in both developed and developing countries internationally. We find that budget reallocation or government bonds are regularly used for losses from natural disaster in developing countries while both government bonds and insurance penetration are used to against catastrophe risks in the developed countries. Finally, we also find that insurance-related instruments are feasible and have been applied in some middle-income countries with assistance from the World Bank.展开更多

To operationalize this approach, this paper carried out a comparative analysis of the naturalness dynamics of the Jacaré-Guaçu and Jacaré-Pepira watershed, based on land use/cover changes and a structural indicator of the landscape, over the 10-year (2004-2014), as support opportunities for improving its environmental planning and management. Land use/cover dynamics were obtained based on screen digitizing of LandSat imagery, using polygon manual digitalization. Naturalness scenarios of the watersheds, over the 10-year (2004-2014), were obtained based on Urbanity Indicator, which evaluates how much the natural landscapes are dominated by altered systems. The total area of watersheds showed a predominantly scenario, induced by anthropogenic agricultural and non-agricultural expansion areas, mainly by conversion of other land use/cover types in sugarcane cultivation. Despite the increase in natural vegetation areas, over the 10-year (2004-2014), Jacaré-Guaçu and Jacaré-Pepira watersheds are far from a sustainable condition. However Jacaré-Guaçu watershed presents a scenario of more committed naturalness due to the increase in Urbanity Index values ≥ 0.7. The historical process of land use occupation for agricultural production remains the main driving force of naturalness changes, occupying more than 70% of the total area of watersheds. These results have significant implications for fast urbanizing municipalities in providing key information about long term land use impact on the watershed structure and function, making it possible for policy makers, scientists and stakeholders to identify land uses which are hindered or enhanced under various scenarios of land use change over the time, and making it possible to explore the trade-offs between them to improve watershed management.展开更多
