Interacting relationships among local and landscape factors and plant richness (total plants, insect-pollinated forbs, non-insect pollinated forbs and graminoids) at five different spatial scales (1–5 km radii around sites).

Analysed using Linear Mixed Effects Models. Note: FT = Farm type (organic or conventional); E/C = Edge/Centre (position in the field); %UG = Percentage unimproved grassland (which reflects an inverse measure of landscape complexity); PC1 and PC2 = first and second principal components from a principal component analysis on soil parameters; N.S. = not significant.

本研究采用线性混合效应模型开展分析。注：FT（Farm type）指农场类型，分为有机与常规两类；E/C（Edge/Centre）代表田块中的边缘或中心位置；%UG（Percentage unimproved grassland）为未改良草地占比，该指标可作为景观复杂度的反向衡量指标；PC1与PC2为针对土壤参数开展主成分分析所得的第一主成分与第二主成分；N.S.（not significant）代表无统计学显著性。
