摘要：利用In VEST模型,以草海国家级自然保护区为例,对2000—2010年保护区生境质量变化进行分析。结果表明:除水域和未利用地外,其他地类变化突出,旱地、草地、城镇建设用地和农村居民点之间转化明显;保护区生境质量整体趋于好转,试验区改善幅度最大,保护区生境质量一直呈现核心区>缓冲区>试验区的特点,核心区和缓冲区生境质量空间变化较小,试验区生境质量空间变化明显,东部和西南部是生境质量改善区,北部主要为生境质量恶化区;退耕还林还草工程实施是生境质量改善的主导原因,城镇用地扩张对部分地区生境质量改善产生一定的负面影响。
We analyzed habitat quality change in Caohai Nature Reserve utilizing the INVEST model from 2000 to 2010. The results showed that other land use types showed significant changes except for water body and unused land, significant area changes could be found among dry land, grassland, built-up land and rural settlements. Hab- itat quality improved in whole nature reserve, particularly for pilot area. The improvement of habitat quality showed core area 〉 buffer area 〉 pilot area. There were little spatial changes of habitat quality in core area and buffer area. Significant spatial changes of habitat quality in pilot area could be found. Improvement regions of habitat quality were located in east and south parts, while deterioration region of habitat quality was situated in north part. Green for Grain Project is the dominant factor resulting in the improvement of habitat quality, while urban land expansion has a negative effect on the improvement of habitat quality.
