摘要: 采用主成分分析(PCA)与熵权相结合的方法,对太子河流域生境质量进行评价,并运用相关分析和冗余分析的方法识别社会经济发展和土地利用方式对生境质量的影响。结果表明: 太子河流域生境质量等级为好的河段占4.35%,较好和一般的河段占91.30%,差的河段占2.17%;生境质量等级较好的河段主要位于上游地区,中游地区生境质量一般,下游鞍山段的生境质量较差;流域社会经济发展和土地利用方式是影响生境质量的主要因素,相关分析和冗余分析均显示生境质量与人口密度、人均地区生产总值、第一产业、第二产业,以及与耕地、建设用地面积比例呈显著负相关关系,而与林地面积比例呈显著正相关;社会经济状况和土地利用方式能分别解释流域生境质量特征的45.7%和39.5%;合理配置产业结构、优化土地利用方式可有效地逐步改善太子河流域生境质量。

Abstract: Combined with principal component analysis and entropy methods, the paper assessed the habitat quality of Taizi River Basin. Correlation analysis and redundancy analysis were used to identify the effects of socioeconomic development and land use pattern on habitat quality. Results indicated that habitat quality across all reaches of Taizi River Basin was 4.35% in good condition, 91.30% in fair condition, and 2.17% in poor condition. The reaches with good habitat quality were mainly located in the upstream of the Taizi River, and those with fair quality in the midstream, and poor quality in the downstream in Anshan. Socioeconomic development and land use pattern were the main factors affecting habitat quality. Habitat quality was negatively correlated with population density, regional GDP per capita, the first and second industry outputs and the ratio of land area for cultivation to construction, whereas it was positively correlated with forest area percentage. Socioeconomic development and land use pattern explained 45.7% and 39.5% of the characteristics of habitat quality, respectively. Our results suggest that the habitat quality in Taizi River Basin may be improved by rationally adjusting industrial structure and optimizing land use pattern.
