Research on this field will play a significant role in rural economic development of Guizhou Province. Taking the observation data from 1999 to 2009 in 10 fixed observation villages in Guizhou Province, we carried out empirical survey and analysis on land scale and use structure, scale and composition of fixed assets for production, level and composition of operational income, and level and composition of financial revenue and expenditure at village level. Finally, we put forward conclusions and recommendations.展开更多

The result shows thatpoverty-stricken areas in Hebei Province distributedconcentratedly and the areas decreased during1986~2000, the net income per peasant was on therise with an increasing speed in off-poverty countiesbeing slightly higher than that in poverty-strickencounties, but the growth rate was extremely unstable,rising slowly in off-poverty counties while droppingin poverty-stricken counties. The main driving forcesthat influenced temporal and spatial changes wereeconomic development of the whole province,ecological environment quality, infrastructureconditions and radiation of the key city. On thisbasis, some anti-poverty countermeasures suitable tolocal conditions are proposed.展开更多

Usually there are many hydrogeological units in a mining area,and the hydrogeological conditions are very different from that of most northern mining areas in China. In view of the uniqueness of mining areas in Guizhou Province,taking Zhijin area of Zhina mining area as an example,the planning characteristics of mining areas and characteristics of groundwater environment in Guizhou Province were analyzed firstly,and then the characteristics and key considerations of groundwater environmental impact assessment in mining areas of Guizhou Province were studied. For example,when the height of water flowing fractured zone,impact radius,and the amount of water resources affected are calculated,it is necessary to analyze and evaluate as many typical mines as possible. The impact on springs as the sources of residents' drinking water should be analyzed one by one.展开更多

From the whole society,the key point is the development of the rural economy,and the development of the rural economy depends on the economic development of rural households. The income from rural labor force transfer has become the main income source and accounts for more than half of rural household income,which will play a major role in survival and development of rural households.展开更多

The hydrogeochemistry due to mining activities and naturalmineralized processes present some differences whose comparison can indicate a good understanding of theinfluence of mining on the environment. This ongoing study aims at the hydrogeochemistry of toxic metals in the Au-As-Hg-Tl metallogenicbelt of Huijiabao anticline in southwest Guizhou, China. The presently-mined Lanmuchang mercury-thallium deposit with a Hg-mining history of about 350 years containing one of the world’s highest concentration of thallium and the to-be-mined Yanshang gold deposit enriching high concentration of toxic metals have been chosen to study the hydrogeochemistry of toxic metals. The groundwater samples werecollected from the shallow aquifer in terms of spring, domestic well and karstic cave whereas the surfacewater was only sampled downside the surface drainage leaching the mine waste at Lanmuchang.
