摘要: 基于高分辨率卫星影像数据,利用遥感、GIS技术获取黑龙江省肇源县内自然资源与生态地质环境各因子分布现状数据,其中:耕地2 541.75 km2、林地161.88 km2、草地349.00 km2、河流128.05 km2、湖泊215.80 km2、沼泽109.17 km2、其他水域84.65 km2、建设用地191.25 km2、未利用地329.94 km2;湿地1 334.54 km2、荒漠化土地775.47 km2。利用地类覆盖率、人均占有量以及景观指数(破碎度指数、平均斑块分形指数、分形维数、多样性指数、均匀度指数)量化分析后,得出两类生态地质环境因子中湿地资源尤其是自然湿地受人类活动干扰程度较大、荒漠化土地受人类活动干扰程度较小的结论。并选取老山村等典型地区进行了多期次遥感动态监测及野外核查,揭示了松嫩低平原典型地区目前存在的湿地退化、土地荒漠化等生态地质环境问题。
