目的 考察杠柳的生長(zhǎng)發(fā)育變化、形態(tài)特征、群落結(jié)構(gòu)及其種類(lèi)組成等，明確各物候期的標(biāo)志性特征，揭示生態(tài)環(huán)境對(duì)植物形態(tài)形成的影響。方法 通過(guò)分層抽樣法，設(shè)置野生、栽培品的樣地、樣方，結(jié)合測(cè)量、記錄、對(duì)比分析等方法，系統(tǒng)考察杠柳的生態(tài)生物學(xué)特性。結(jié)果 杠柳的物候期可劃分為萌動(dòng)期、展葉期、始花期、終花期、結(jié)果期、果實(shí)成熟期、落葉期、枯萎期；其植物形態(tài)呈藤本、灌木狀、蔓性灌木狀；藤本杠柳的植被類(lèi)型為落葉闊葉林，群落各層片的優(yōu)勢(shì)種分別為大葉白蠟、牛迭肚、藍(lán)萼香茶菜；蔓性灌木、灌木者為灌草叢植被型，荊條＋酸棗、鬼針草＋白蓮蒿分別是群落各層片的優(yōu)勢(shì)種。結(jié)論 杠柳物候期各階段的變化特征明顯；植物形態(tài)多樣性的形成與其生存環(huán)境密切相關(guān)，主要取決于氣候因子和土壤因子，為進(jìn)一步探索杠柳的生態(tài)生物學(xué)特性及其規(guī)范化培植提供科學(xué)依據(jù)。

Objective To study the changes in the growth and development, morphological characteristics, community structure and species composition of Periploca sepium Bunge to clear the phenological phase characteristics, reveal the impact on plant morphogensis by ecological environment. Methods Stratified sampling method and setting wild, cultivated plots, and quadrats together with the analysis of measuring, recording, contrast were used in this experimental program to study the ecological and biological characteristics systematically. Results The phenological phase of P. sepium could be divided into germination period, leaf expansion, flowering, final flowering, fruiting period, fruit ripening, defoliation, withering period; The plant morphology was fujimoto, shrubby, and trailing shrubby; The vegetation type of fujimoto P. sepium is deciduous broad-leaved forest, and the dominant species are Fraxinus rhynchophylla, Rubus crataegifolius, and Rabdosia japonica var. glaucocalyx; trailing shrubby and shrubby are shrub vegetation type, the dominant species are Vitex negundo var. heterophylla + Ziziphus jujuba var. spinosa, Bidens bipinnata + Artemisia sacrorum. Conclusion The change characteristics of the various stages of phenological phase are significantly; the plant morphological diversity is closely related to the living environment, especially climatic factors and soil factors, which provides a scientific basis for further exploring the ecological and biological characteristics and standardized cultivation.
