以2009年土地利用调查数据和DEM数据为数据源,运用核密度估计、探索性空间数据分析和空间变差函数等方法,从分布、规模和形状3方面对秦巴山区的竹溪县乡村聚落空间格局展开研究,并分析不同地形梯度下的乡村聚落分布特征。结果表明:①竹溪县乡村聚落为集群分布,拥有多条核密度高值分布带,表现出“中东部密集、北部次密集、南部密集程度较低”的特征;②乡村聚落用地规模普遍偏小,呈现出“北部较大,中、南部偏小”的分布格局;③乡村聚落斑块形状的不规则程度较高,总体上看,中部和南部聚落斑块的不规则程度高于北部。南一北方向上乡村聚落形态分布的均质性最佳,东一西和东南一西北方向上乡村聚落形态...

The first large-scale solar air-conditioning and hot water system in China was constructed in Jiangmen city of Guangdong province. Efficient flat plate solar collectors and a 100 kW two-stage absorption chiller are used in the system. It is a low temperature (65-75 °C) heat source driven LiBr/H2O absorption refrigeration system which can be used for both refrigeration and air conditioning. Some parameters and running results were reported. It is significa...
