摘　　要：以兰州市为研究对象,探究生境特征的村镇聚落分类并进行生态环境质量评价,旨在明确村镇聚落分类与生态环境质量的联系,为村镇建设发展与资源利用提供参考。结果表明:(1)兰州市村镇形成“五大类九小类”聚落类型,其中谷地聚落数量较多,占整体的59.10%;其次为丘陵聚落,平川与山地聚落数量相差不大,占整体的7.90%和8.48%;高原聚落数量最少。(2)高程是影响聚落分布和环境质量的主要因素,平川与谷地聚落集聚于河岸两侧,数量较多且生态环境较差;山地与高原聚落生态环境较好,但村镇聚落较少。村镇聚落与生态环境质量呈显著负相关,生态环境特征分析结果与生态环境质量评价结果一致性较高。Taking Lanzhou City as the subject of study,this paper explores the classification of rural settlements based on environmental characteristics,and conducts an assessment of ecological environmental quality.The aim is to clarify the connection between the classification of rural settlements and the quality of the ecological environment,providing references for rural construction development and resource utilization.The results show that:(1)Rural settlements in Lanzhou City form“five categories and nine types”of settlement types.Among them,valley settlements are more numerous,accounting for 59.10%of the total;followed by hill settlements,with plain and mountain settlements not significantly different in number,accounting for 7.90%and 8.48%of the total,respectively;plateau settlements are the least common.(2)Altitude is a primary factor affecting settlement distribution and environmental quality.Plain and valley settlements are clustered on both sides of the riverbanks,and are numerous but with relatively poor ecological environments;mountain and plateau settlements have a better ecological environment,but the number of rural settlements is low.There is a significant negative correlation between rural settlements and ecological environmental quality,and the consistency between the results of the ecological environment characteristics analysis and the ecological environment quality assessment is relatively high.
