路基施工总体风险评估方法研究

通过指标体系法系统性地构建了以交叉道路、公路等级、公路服务等级、公路里程等为评估指标的路基施工总体风险评估体系,以定量评估通车情况下公路改扩建路基施工的总体风险,同时利用该体系对某条穿镇一级扩建公路的路基施工总体风险进行了评估,充分验证了该体系的可靠性、准确性和可操作性,可以为同类项目的路基施工风险评估提供借鉴。

A study on the bioenergy crop production function of land use in China

Based on the analysis of the bioenergy crop production function of land use,combined with the status quo of Chinese land use,the cultivation of energy plants and the bioenergy crop production function of land use had been analyzes and discusses in this paper.Results show that there were a lot of unused lands and marginal lands which can be planted bioenergy crops to perform the bioenergy crop production function of land use with great potentials;and currently there were no food production problems.Therefore,it was very important for China to emphasize bioenergy crops planting in order to fully use land resources in our country,moderate the energy crisis and increase peasants' income.
