阿克苏河流域绿洲森林景观格局变化及指标分析与评价

Changes of Forest Landscape Pattern and Index Analysis of Oasis in Aksu River Basin

从乡村振兴、美丽村庄的建设需要出发,对阿克苏河流域绿洲森林景观格局变化及指标进行分析与评价,以解决绿洲生态林建设的实际问题。结果表明:采取抽样的方法,利用高分辨率遥感影像数据,测定森林覆盖率为22.57%,影响绿洲森林覆盖率主要林种是经济林。通过分析农防林的带斑比和连接度这2个主要景观评价指标,引入规范的绿洲农防林建设指标,结合现状庇护斑块的大小,规划出理想状态防护林建设数量和长度,计算出阿克苏河流域绿洲防护林存在的差距,发展方向和增长空间数量。

Starting from the needs of rural revitalization and the construction of beautiful villages,the forest landscape pattern changes and indicators in the oasis of the Aksu River Basin were analyzed and evaluated,so as to solve the practical problems of oasis ecological forest construction.Result showz that the sampling method is adopted and the high-resolution remote sensing image data is used to determine the forest coverage rate(22.57%),the main forest species that affects the forest coverage of oasis is economic forest.Through the analysis of the two main landscape evaluation indicators,the ratio and connectivity of agricultural protection forests,introduce standardized oasis agricultural protection forest construction indicators,combined with the size of the current sheltered patches,plan the number and length of the ideal state protection forest construction,and calculate the gap,development direction and growth space of the oasis protection forest in the Aksu River Basin.
