    It is of significance to analyze the marketization level and regional difference in governmental controls on land. This paper, from land market trading structure, estimates the marketization level of China’s provincial areas during 1999 to 2007, and studies their regional difference by means of clustering method. The results indicate a gross low marketization level in China, a slow by fluctuation rising trend. The eastern areas are higher than the central, western and northeastern China, but their difference is becoming small. Based on national 31 provincial areas, 9 areas including Heilongjiang, Shanghai and Jiangsu rank the top, while other 5 areas including Xinjiang and Gansu are lowest in marketization level. At the same time, Tianjin and Shandong are low in land marketization level although they are located in eastern economic developed area, while Chongqing and Sichuan are higher in western China.

    This paper, based on exploration rights transfer background, high risk and high profit characteristics, and strong positive externalities and anisomerous information, demonstrates the bidding, auction and listing system to be fallacious, which leads to a short in exploration rights and a gambling in exploration rights market, making a problem for government. The bidding, auction and listing system aims to be fair formally, but breaks the market rules, always results in a low efficiency in resources allocation in practice and blocks the nation’s target in transferring exploration rights, which shall attract more investors into mining, finding more deposits and increasing a guarantee of mineral  resources. Exploration rights market can not develop in deviation. This paper presents some suggestions and policies as well.

    The farmland non-agricultural conversion is key to regional economic development and eco-environmental protection.Recently, there is a big scale of farmland non.agricultural conversion.To study the changes in ecosystem service values can provide a reference for making policies in sustainable development of land resources and eco-environmental protection. This paper, by means of ecosystem service values and economic values of food production from unit farmland, and 1996—2004 land survey data, estimates and compare the ecosystem service values of farmland non-agricultural conversion, indicates a total 17 450.91 hm2 converted with a decrease in ecosystem service value by 215.47×106 RMB.From different ecosystems, the ecosystem service values decrease most while entertainment culture decreases least; from different land use categories, the ecosystem service values has a biggest loss from plowland and other agricultural land non-agricultural conversion.

     This paper, according to 2006 IPCC Guidelines for National Greenhouse Gas Inventories, calculates the 1992—2007 carbon emission in Guangzhou, with results indicating an increase in gross carbon emission and carbon emission per capita while a decrease in carbon emission intensity, from 0.419 kg/RMB in 1992 to 0.275 kg/RMB in 2007, an average 2.28% in yearly decrease. The carbon emission structure reveals that Guangzhou energy consumption structure chiefly on coal has little change From economic structure, carbon emission intensity keeps little change in the first industry, rises followed by falling in the second industry, and rises rapidly in the third industry and in living consumption.An accretion in population and economy are two factors for carbon emission, while an decrease in energy intensity can effectively control the carbon emission. This paper gives suggestions decreasing carbon emission by controlling population, adjusting industrial structures, decreasing energy intensity and increasing energy use efficiency.
