摘　　要：为探索石漠化区光伏场区植被恢复策略,开展遮荫程度逐渐增加的阵列行间对照区和前檐、后檐、组件下方遮荫区植物8个叶功能性状差异和响应机制研究。结果表明:与阵列行间相比,檐下(前、后檐)植物叶鲜质量、叶干质量、叶面积、叶体积和叶组织密度升高,比叶面积降低;组件下方植物叶含水率、叶鲜质量、比叶面积升高,叶组织密度、叶干质量降低;檐下和组件下方植物叶性状种间变异总体上分别呈降低和增加趋势,但叶厚种间变异随遮荫程度增加而增大,叶含水率种间变异最小。据此,阵列行间、组件下方、檐下植物分别采取保守、积极、积极与保守协同的生态策略,研究成果可为植被恢复物种筛选提供科技支撑。In order to explore the vegetation restoration strategy of photovoltaic station in rocky desertification area,current experiment aims to identify the differences of eight leaf functional traits in 4 typical habitats,i.e.,the inter,front eaves,rear eaves,and under of the photovoltaic panels.The results indicate that the influences of photovoltaic panels shading on plants compared with the plants at inter-panels as follows:(1)Leaf functional traits show detectable changes for the plants at front and rear eaves,i.e.,the leaf fresh weight,leaf dry weight,leaf area,leaf volume and leaf tissue density increasing,whereas the specific leaf area decreases;the leaf water content,leaf fresh weight and specific leaf area increasing for the plants under the panels,whereas the leaf tissue density and leaf dry weight decrease;(2)Generally,the leaf functional traits interspecific variations decrease at front and rear eaves,whereas increase under the panels;however,the interspecific variation of leaf thickness increases with shading and the leaf water content shows a minimal fluctuation.In short,plants tend to adopt active and conservative ecological strategies,but conservatism mainly at front and rear eaves;the plants under the panels tend to adopt active ecological strategy to enhance the resource acquisition;the plants at inter-panels tended to adopt conservative ecological strategy.Thus,the combination of plant leaf functional traits implicate the difference in ecological strategies in changed habitats,and understanding ecological strategies provide insight into vegetation restoration of photovoltaic power station in rocky desertification area.
