    With the rapid economic growth and urbanisation process, a large amount of cultivated land has been permanently transformed into urban land. The protection of cultivated land has received widespread attention, and ecological compensation has been an effective means of restraining the decrease in cultivated land. Different from previous approaches to and methods of studying cultivated land’s ecological compensation, this study proposes a new behavioural perspective.

    The structural index is an important quantitative parameter for revealing the structural properties of loess. However, there is no a widely accepted measurement method for structural index at present. This study aims at presenting a novel method for obtaining the loess structural index (LSI), based on the application of computed tomography (CT) scanning techniques and laboratory physico-mechanical tests. The mountainous area of Lvliang in northwest China was taken as the study area, and Late Pleistocene loess samples were taken from various sites in the region.

    The Qinghai-Tibet Plateau (QTP) is an area sensitive to global climate change, and land use/land cover change (LUCC) plays a vital role in regulating climate system at different temporal and spatial scales. In this study, we analyzed the temporal and spatial trend of precipitation and the characteristics of LUCC on the QTP. Meanwhile, we also used the normalized difference vegetation index (NDVI) as an indicator of LUCC to discuss the relationship between LUCC and precipitation.

    Environmentally friendly technologies have long been recognized as a widespread phenomenon working within the functions and performance of farms. Farmer’s cooperative organization might profoundly foster the environmentally friendly technologies (EFT) and availing competitive advantage to the farmer.

    Farmers' ability to leave agriculture is an important and debated topic in China and other countries. Many scholars believe China's unique land tenure policies prevent farmers from leaving agriculture. This paper examines the hypothesis that China's land tenure system deters exit from agriculture using household level data from Northeast China.

    China, a country developing at unprecedented levels, has experienced drastic changes throughout its recent economic history. Of primary interest is the continuing development and improvement of the rural agricultural sector, with even the slightest changes in this sector having dramatic ripple effects on rural economies. Estimates of rural households involved in agricultural production range from 65 to 70 percent (de Brauw & Rozelle, 2008; Rozelle, Taylor, & de Brauw, 1999).

    There is a trend to acquire high accuracy land-cover maps using multi-source classification methods, most of which are based on data fusion, especially pixel- or feature-level fusions. A probabilistic graphical model (PGM) approach is proposed in this research for 30 m resolution land-cover mapping with multi-temporal Landsat and MODerate Resolution Imaging Spectroradiometer (MODIS) data. Independent classifiers were applied to two single-date Landsat 8 scenes and the MODIS time-series data, respectively, for probability estimation. A PGM was created for each pixel in Landsat 8 data.

    China’s traditional urban land system is established in highly centralized planned economy. This system negates functions of value law and economic law fundamentally, so it is not favorable for establishment of market mechanism and development of market economy. This study took Marx’s ground rent theory as guidance, combined existing problems of China’s land use system, and made analysis on innovation of China’s urban land system from property right system, land market and land price.

    This study assesses the determinants of forest land allocation to households in the forest tenure reforms in China in the period 1980-2005 using data from three provinces in Southern China; Fujian, Jiang Xi and Yunnan. Furthermore, it assesses the current level of tenure security on forest land and how this tenure security is affected by past and more recent policy changes.
