Study on the abandonment of sloping farmland in Fengjie County,Three Gorges Reservoir Area,a mountainous area in China

The farmland abandonment phenomenon in mountainous areas is a recent change in relationships between man and land that emerged in China's land-use transition. Revealing spatial distribution characteristics and influence factors of sloping farmland (SF) and abandoned farmland (AF) in mountainous areas is conducive to rational allocation and optimization on local land resources. This paper investigated regional distribution features of SF and AF in the hinterland of the Three Gorges Reservoir Area (TGRA) using high-resolution remote sensing images, ArcGIS spatial analysis, and statistical methods. The results found that the spatial distribution of SF and AF has an approximate characteristic under different topography, location, or accessibility backgrounds. However, within different spatial coupling relationships between SF and AF, influencing mechanisms of farmland abandonment are significantly different. The diversity of geographical locations reflecting natural and social contexts is an essential reason for this differentiation. Moreover, dominant influencing factors of farmland abandonment in the study area are natural factors such as slope and farmland quality. Socioeconomic factors, including distance to road, peasant income, and labor force proportion, guide the distribution and trend of farmland abandonment to varying degrees. Finally, four modes of farmland abandonment in TGRA have proposed and suggested that the corresponding plans for SF consolidation should be proposed based on fine classification, which is of great significance for farmland utilization and rural revitalization in underdeveloped mountainous areas.

三江平原的鹤类资源及保护

三江平原1958年开始有计划开发,到1990年代末,湿地仅余1.6×104hm2,且极度破碎,环境恶化,有些种类已绝迹,现存种类亦处于濒危状态。丹顶鹤由开发初期的数千只,减少到1990年代中期的百余只。挠力河流域2000年有丹顶鹤103只。2001年该区丹顶鹤繁殖数量约为200只,迁徙数量为800只左右;白枕鹤繁殖数量为70~90只,迁徙数量为700~800只;白头鹤迁徙数量为100左右;其它鹤类数量极少。影响鹤类分布的主要原因有栖息地面积减少、人为干扰严重、环境污染和食物减少等。

Theoretical Framework and Method of Detecting Accounting Fraud

Accounting fraud has never been rooted out, which brings a lot of trouble to our society. Only through strengthening user＇s ability to discern, decode and feedback the false information can we maximally understand the information behind. Therefore, devoting ourselves to setting up a framework of detecting the accounting fraud has become a feasible and efficient way to solve this problem. Based on the ＂Three Elements Theory＂, this paper demonstrates a new way to discern the fraud by researching its origins. The authors combine the theoretical model and the applied technology together to design a fraud recognization system.
