摘要:
为改善川中丘陵区柏木人工林林下植物多样性与土壤现状,以当地柏木人工林为研究对象,分析目标树经营1年后,3种不同目标树密度(100、150、200 株/hm2)林下植物多样性和土壤理化性质的变化情况。结果表明:与对照林分相比,目标树经营初期,三种不同目标树密度下灌木层植物多样性各指数显著增加(P < 0.05),喜光植物增多,林地内出现多种生活型,草本层多样性指数、生态优势度指数和均匀度指数均显著降低(P < 0.05);土壤pH与速效钾含量显著降低(P < 0.05),非毛管孔隙度、全氮、水解氮、全磷、有效磷和有机质显著增高(P < 0.05);氮和磷是植物的主要限制因子,植物各多样性指数与全氮、全磷、有效磷密切相关,非毛管孔隙度、毛管孔隙度和速效钾含量与草本层各多样性指数最为密切。本研究表明,目标树经营初期能够增加灌木层植物多样性、提高草本层物种丰富度与改善土壤理化性质,土壤因子与林下植物多样性的变化密切相关。(图3表6参37)
Abstract:
In order to improve the undergrowth plant diversity and soil factors of Cupressus funebris plantations in hilly region of central Sichuan , this paper used target tree management to clarify the e arly effects of undergrowth plant diversity and soil physicochemical properties of the local forest ecosystem . In this study, Cupressus funebris plantations were used as the research object to analyze the effects of three different target tree densities (100 target trees per hectare, 150 target trees per hectare, and 200 target trees per hectare) on undergrowth plant diversity and soil physicochemical property after one year target tree management. The results showed that compared with the control (CK): In the early stage of target tree management the plant diversity of shru b layer increased significantly ( P < 0.05). The number of sun plants increased and various life forms appeared in the woodlands. Simpson, Shannon-wienner , and pielou indexes of herbs decreased significantly ( P < 0.05). Under the three different target tree densities, soil pH and available potassium content decreased significantly ( P < 0.05), and non-capillary porosity, the content of total nitrogen, hydrolysable nitrogen, total phosphorus, available phosphorus and organic matter increased significantly ( P < 0.05). Nitrogen and phosphorus are the main limiting factors of plants, plant diversity indices were closely related to total nitrogen, total phosphorus, and available phosphorus. Non-capillary porosity, capillary porosity and available potassium content were most closely related to the diversity indices of herb layer. The results showed that in the early stage of target tree management could increase the diversity of shrub layer, the richness of herbaceous layer and improve the soil physicochemical properties, there were closed correlation between soil factors and undergrowth plant diversity.
