摘要:

基于2013—2022年NDVI、NPP、CLCD及地形坡度等多源遥感数据和计算获取的NDVIS和CV生态特征参数,构建涵盖NPP、CV、NDVIS和土地利用转移矩阵的生态特征耦合体系,对科尔沁沙地生态系统进行功能分区。结果表明:涵养区面积4 435.3 km²,以森林为主(91.7%),集中分布于大兴安岭南缘和努鲁儿虎山北缘丘陵区,水体湿地主要分布于水库及湖沼区;稳定区面积59 471.3 km²,以农田(62.6%)和草地(35.4%)为主,农田集中分布于沙地中、东和南部,草地在北部地区集中分布;恢复区面积27 979.8 km²,以草地为主(97.2%),除东、南部和西辽河沿岸农耕为主及北部森林涵养区外,其他地区逆转态势均较为显著;退化区面积22 731.8 km²,以轻度退化为主(18 483.5 km²),集中于东、南部农田及北部大兴安岭南缘,农田和草地向低植被覆盖用地转化最为活跃,通榆县西北部水体发生重度退化;生态脆弱区面积 8 472.2 km²,以不透水地表(54.8%)和荒地(44.9%)为主,受自然条件与人类活动双重驱动。

Abstract:

Based on multi-source remote sensing data, including NDVI, NPP, CLCD, topographic slope, and derived ecological characteristic parameters (NDVIS and CV) from 2013 to 2022, this study constructs an ecological characteristic coupling system incorporating NPP, CV, NDVIS, and land use transfer matrices to conduct functional zoning of the Horqin Sandy Land ecosystem. The results indicate that: The conservation zone covers an area of 4 435.3 km², predominantly forest (91.7%), concentrated in the southern foothills of the Greater Khingan Mountains and the northern hilly areas of the Nurulhushan Mountains, with water bodies and wetlands mainly distributed in reservoir and marsh areas. The stable zone spans 59 471.3 km², primarily consisting of farmland (62.6%) and grassland (35.4%). Farmland is concentrated in the central, eastern, and southern parts of the sandy land, while grassland is predominantly distributed in the northern region. The restoration zone covers 27 979.8 km², mainly grassland (97.2%). Except for the eastern and southern regions, the areas along the Xiliao River dominated by agriculture, and the northern forest conservation zone, other areas show a marked reversal trend. The degradation zone occupies 22 731.8 km², with mild degradation being predominant (18 483.5 km²), concentrated in the eastern and southern farmlands and the southern foothills of the Greater Khingan Mountains in the north. The conversion of farmland and grassland to low vegetation cover land uses is most active, and severe degradation of water bodies is observed in the northwestern part of Tongyu County. The ecologically fragile zone covers 8 472.2 km², dominated by impervious surfaces (54.8%) and barren land (44.9%), driven by both natural conditions and human activities.
