【摘要】 研究小尺度撂荒耕地景观格局有利于准确掌握撂荒耕地特征并进行空间格局调控,提高耕地利用率,为发展农村经济提供重要依据。利用ArcGIS 10.1及景观指数,采用农村土地承包经营权确权数据,对不同特点村庄的撂荒耕地从不同景观层次进行斑块特征及空间特征分析。结果表明,在斑块层次上,城边村和偏远村与工矿产业村、农产业村相比,大部分撂荒地块面积小,分布离散,但是各村形状都呈简单规则分布;与斑块层次相比,类型层次撂荒地块斑块面积较大、破碎程度较小,地块形状较复杂,聚集程度更大;在类型层次中,相同行政尺度下不同类型村庄撂荒耕地景观格局特征存在明显差异性,并针对不同特点的村庄提出有针对性的措施。更多还原

【Abstract】 The purpose of this study is to accurately graspe the characteristics of abandoned farmland and regulate the spatial pattern, improve the utilization rate of cultivated farmland, which provides an important basis for the rural economy development of the small scale abandoned farmland landscape pattern. Using ArcGIS 10.1 and landscape index, the patch characteristics and spatial characteristics of abandoned farmland of different landscape levels in different characteristics villages are analyzed based on the data of rural land contractual management rights. The results show that compared with industrial and mineral industry villages and agricultural industry villages, most abandoned farmland in urban and remote villages have smaller area and dispersed distribution at the patch level,but the shape of each village is simple and regular distribution. Compared with the patch level, the patch area of abandoned farmland at the class level is larger, the fragmentation degree is smaller, the shape of the patch is more complex, and the degree of aggregation is larger. At the class level, there are obvious differences in the landscape pattern characteristics of different characteristics of villages under the same administrative scale, and targeted measures are proposed for villages with different characteristics.更多还原
