摘要:

探究2000—2015年间酉阳县土地利用演变特征规律及地理生态过程,为实现区域土地资源可持续利用提供科学依据。本研究运用图谱理论信息学探究区域土地利用空间分布特征和时空演变规律。结果表明:15年间研究区不同地类呈现不同的发展趋势,土地利用结构主要以林地和草地为主,面积比例分别为86.79%、88.54%、86.13%和85.86%,林地占据一定优势地位。3个时序单元的主要图谱单元类型及面积存在一定的差异性;土地利用涨势和落势图谱中,林地涨势面积最大,占新增面积比例的38.67%,草地落势面积最大,占萎缩面积的比例为38.03%。该研究为今后酉阳县土地利用可持续发展和生态建设提供理论依据和科学支持。

Abstract:

The study aims to explore the characteristics of land use evolution and geographic ecological process in Youyang County from 2000 to 2015, and provide a scientific basis for the sustainable use of regional land resources. We used map theory informatics to study the spatial distribution characteristics and temporal and spatial evolution of regional land use. The results showed that different land types in the study areas had different development trends during the 15 years. The land use structure was mainly forestland and grassland with the area ratio of 86.79%, 88.54%, 86.13%and 85.86%, respectively, and the forestland had a dominant position. There are certain differences in the types and areas of the main graph units of the three sequential units. In the map of land use rise and fall, forestland had the largest rise area, accounting for 38.67% of newly increased area, and grassland had the largest fall area, accounting for 38.03% of the shrink area. The research could provide certain scientific support for the sustainable development of land use and ecological construction in Youyang County in the future.
