摘要: 区域土地利用格局主要受经济、政策和气候条件的影响,土地利用格局的转变会影响区域生态环境质量。通过对遥感影像目视解译、现场勘查等方式,形成2010—2018年9期土地利用数据,从时空格局、变化强度、土地利用转移矩阵、生态系统格局方面对辽河保护区土地利用的空间分布与时空变化进行分析。结果表明:2010年(保护区划定初期)辽河保护区土地利用类型主要为湿地、耕地和水体,三者合计占保护区面积的81.3%,2011年保护区内耕地面积占比由33.5%降为8.3%,草地面积占比由0.4%提高至23.5%;2010—2018年,辽河保护区综合土地利用动态度整体呈下降趋势,其中,2011年、2014年和2018年综合土地利用动态度较高,各土地利用类型之间转变相对剧烈;单一土地利用动态度变化较大的土地利用类型为耕地、草地和林地;2010—2018年,辽河保护区景观格局聚集度基本稳定,连通性略有提升。保护区的划定及相关措施的落实促进了保护区内生态用地面积的增加,对保护区生态恢复起到了积极的作用。Abstract: The regional land use pattern is mainly affected by economic, policy and climate conditions. The change of land use pattern will affect the quality of regional ecological environment. Through visual interpretation of remote sensing images, on-site exploration and other methods, a total of 9 periods of land use data from 2010 to 2018 were formed. Considering from temporal and spatial pattern, change intensity, land use transfer matrix and ecosystem pattern, the spatial distribution, temporal and spatial changes of land use in Liaohe Conservation Area were analyzed. The results showed that Liaohe Conservation Area was dominated by wetlands, cultivated land and water bodies at the beginning of the reserve designation in 2010, accounting for 81.3% of the total area. With the establishment of the conservation area in 2011, the proportion of cultivated land decreased from 33.5% to 8.3%, and the proportion of grassland increased from 0.4% to 23.5%. From 2010 to 2018, the dynamic degree of comprehensive land use in Liaohe Conservation Area showed a downward trend,among which the dynamic degree of comprehensive land use was higher in 2011, 2014 and 2018, and the transformation among various land use types was relatively fierce. The land use types with larger dynamic degree of single land use were cultivated land, grassland and forestland, etc. From 2010 to 2018, the aggregation degree of landscape pattern of Liaohe Conservation Area was basically stable, and the connectivity was slightly improved. The establishment of Liaohe Conservation Area and the implementation of relevant measures had promoted the increase of ecological land area and played a positive role in the ecological restoration of the conservation area.
