中文摘要:

对黑龙江省绥化市的6个村落、九三垦区鹤山农场的8个村落和嫩江县双山镇的蔡窑村进行实地考察。依据鹤山农场1980-1995年气温、日照时数、风速、降水量和≥5级风日数的气象资料,同时考虑到地形、土壤等因素,分析了东北漫岗区村落分布的特征,即:日照和太阳辐射影响了村落分布的坡向,就不同坡向而言,村落分布数量大小顺序为:东南坡、西南坡、东北坡、西北坡;风影响室温,并可能对房屋造成破坏,故大部分村落分布在坡中部以下;降水量和土壤特性决定了村落的分布下限;地理环境因素和人的选择性、能动性共同决定了东北漫岗区村落呈狭长形沿坡分布。

英文摘要:

Human settlement reflects geographical environment of a region. Field investigations were carried out of 5 villages in Suihua City,8 villages of the Heshan Farm in the 93 Reclamation Zone and Caiyao Village in Shuangshan Town, Nengjiang County in Heilongjiang Province. Based on the meteorological data, such as temperature, daily sunlight hours, wind speed, precipitation and frequency of wind over Class 5, etc. , of the Heshan Farm in 1980-1995, and some other factors,like topography and soil,characteristics of the distribution of villages in the hilly northeast China were analyzed. Resuits show sunlight hours and solar radiation decides slope aspect of rural settlements. In terms of number of rural settlements ,slope aspects are in the order of southeast 〉 southwest 〉 northeast 〉 northwest. Wind affects indoor temperature and may possibly damage buildings so that most rural settlements lie in the middle and lower parts of a slope. Soil characteristics and precipitation determines the lower limit of the distribution of rural settlements. These geographical factors jointly decide that a village in that region spreads out like a long narrow stripe along the slope.
