天山北坡经济带耕地变化的驱动力研究

根据天山北坡经济带的统计资料，分析了1990-2004年该区域耕地面积变化的趋势。运用主成分分析法对影响耕地面积变化的人口因素、经济因素、收入消费因素和技术进步因素四类13个指标进行定量研究。在此基础上，建立了多元线性回归模型。     

Assessing the Influence of Traffic Impact Assessments on Land Use Development and Decision Making

Rapid urbanisation and land use planning in cities and countries worldwide have an impact on traffic related risks to society as a whole. Strategic planning decisions made during land use development approvals can affect the performance of transport infrastructure significantly impacting on community safety. One major contributor to the decision-making process is Traffic Impact Assessment （TIA） undertaken prior to development approval. The content of each TIA process differs according to the type of development and its geographical location. The paper presents a brief overview of the strategic decision-making process adopted in Australia in land use development approvals. Using a selected case study area, the importance of the TIAs to the decision-making process is demonstrated. Further, the paper presents the observed differences between the facts presented in TIAs completed by four different consultants and the influence of the new development in the community safety. Traffic records after the new development indicate that the accidents have almost doubled after the new development. It is noted that the current TIA process requires significant changes to ensure that the influence of the land use development decisions are captured correctly to ensure informed strategic decision-making. A set of recommendations to overcome the shortcomings of existing planning and TIA designing process is presented.     

新疆天山北坡经济带土地利用结构变化的驱动力分析

天山北坡经济带地处欧亚大陆腹地,地缘关系与战略地位极其突出,但近年来土地利用结构变化显著:草地被大面积开垦,土地退化,生态环境恶化等。本文通过对天山北坡经济带2001年-2004年土地利用变化情况进行分析,阐明了土地利用结构变化的驱动力因素,从而为新疆天山北坡经济带制定有关土地政策和调整计划提供借鉴,也为土地资源可持续利用和生态环境保护奠定基础。
