The paper presents a critical issue to establish a complete ecological compensation mechanism in order to develop and actualize the function of agricultural carbon sink, which is analyzed with the potential capacity of carbon emission reduction. A strategy is put forward to improve the mechanism of ecological compensation to agricultural carbon sink.
Biomass is an important source of renewable energy that has the potential to reduce greenhouse gas emissions. Some food crops, such as corn, can be used as feedstock for bioenergy production. Under limited cultivated land resources, this may lead to increased food prices due to resource competition between food and fuel. Some energy crops, such as switchgrass and hybrid poplar, can be grown on marginal...
Based on the analysis of the bioenergy crop production function of land use, combined with the current situation of Chinese land use, this paper analyzes and discusses the cultivation of energy plants and the bioenergy crop production function of land use. Results show that there is a lot of unused land and marginal land to plant bioenergy crops to perform the bioenergy crop production function of...
The ecological protection of the farmlands in China is being confronted with a lot of problems such as soil and water erosion, land degradation at present. Therefore farmland eco-compensation is becoming a question of common interest. Based on the analyses of the major problems and their origins in the farmland protection in China, the paper discusses the concerned policies including relative rules...
The purpose of this study is to define the connotation and establishing a scientific evaluation system of intensive agricultural land. Methods of documentation and synthesis were employed. The results indicate that the intensive level of agricultural land use includes the index of labor, index of capital and index of technique. And at the same time, the assessment index system of intensive use of...
Pesticides are widely used in China for crop protection. Econometric analysis showed the magnitude of the chronic health effects and health costs to be directly related to pesticide exposure, and accumulative pesticides has led to serious pollution to the environment. This study was conducted on a random sample of 150 rice farming households to collect information on their knowledge, attitude, and...
Water resource is a crucial factor in social and economic development and ecological protection in arid and semi-arid areas. The unbridled development and use of water resources in the lower reaches of the Tarim River over the last 50 years have led to a serious ecological degradation: (1) groundwater level drop. (2) water quality deterioration. (3) land desertification and frequent natural disasters...
A ten-day interval of satellite data (NOAA/AVHRR) between 1981 and 2001 were used to investigate the Vegetation dynamic in Northern-Tibet Plateau (NTP), China. The relationships between NDVI and climatic parameters were analyzed in six counties of NTP. And the human activities factors such as population also tested in this study. The result shown that the prominent increase and decrease of NDVI occurred...
