Framework Construction for Planning and Design of Tropical Leisure Agricultural Park

Leisure agriculture in Hainan Province has remained in the development stage,so it is necessary to construct the framework for the planning and design of tropical leisure agricultural park.On the basis of analyzing planning conditions for the tropical leisure agricultural parks in Hainan,planning principles,overall concept,land use and functional layouts,spatial organization and landscape features,road system,comprehensive pipeline design and vertical planning,the framework for the planning and design of tropical leisure agricultural parks in Hainan is constructed.

基于热管的自燃煤矸石山温度变化规律研究

针对煤矸石山自燃引发的各种危害,采用热管被动降温技术治理,并对煤矸石山内部温度进行为期1a的动态监测,确定了自燃煤矸石山全年的降温效果。借助等温线图探究了矸石山内部温度场的演变趋势,分析了温度变化的季节性特征。结果表明:通过采用热管被动降温技术,自燃煤矸石山全年81%的监测点温度有不同程度的降低,超过1/3的监测点降温幅度达到100℃以上,降温效果明显;随着时间的推移,不同深度水平方向上的高温中心所占面积不断减少,且均有向低温区域持续蔓延的演变趋势;温度变化具有明显的季节性特征,整体为冬季降温比率最大,夏季降温最差,且浅层受外界环境变化的影响较大,浅层温度随季节的变化特征较深层更明显。
