秦岭北麓乡村植物景观与物种丰富度的关系OACSTPCD

In this study,five villages in the northern foothills of Qinling Mountains in Shaanxi Province were selected as the test area,and multiple linear regression and correlation analysis were used to explore the influence of plant richness on rural landscapes in the rural areas of the northern foothills of Qinling Mountains.The results show that the villages far from towns have single plant diversity and low material richness.The evaluation index system of rural landscape far from towns scores low.Multiple linear stepwise regression analysis shows that Pielou evenness index has significant positive correlation with social effect,aesthetic effect and ecological quality and Menhinick richness index has significant positive correlation with aesthetic effect,ecological quality and cultural value.Based on the above analysis,it is proposed that we should be based on resource advantages,select advantageous characteristic plants suitable for the development of rural landscape,comprehensively improve the cohesion of rural landscape,scientifically maintain rural landscape with high ornamental value,and create rural tourism experience services,so as to promote sustainable rural development while maintaining rural environmental governance,and provide references for the research on plant diversity in rural landscape construction.
