摘要:
:草花混播是城市中人工混播草本花卉种子以模拟 天然草地景观的尝试,是目前国内外景观研究的热点之一。 但草花混播设计时,种类选择盲目性大、杂草清除成本高、 景观持续性差等难题,严重限制其建植与推广。将生态学 CSR(Competition,Stress,Ruderality)理论与草花混播 紧密结合,指出要构建多样性丰富、杂草少、群落竞争较小的 稳定群落,应施加环境压力、减少环境干扰,并降低优势种竞 争强度,促使其向胁迫耐受型转化。在北京地区大量播种试验 基础上,基于植物不同的CSR策略类型,从群落结构、配置模 式等角度提出混播种选择的建议,为混播物种的选择和应用提 供理论支撑和实践指导。

Species Selection and Community Construction of Flower Meadows Based on CSR Theory
JIANG Yarong,YUAN Tao,WU Luyao
Abstract:
Flower meadows mixing various flower seeds are artificial simulations of natural grassland in the urban city, and are one of the hottest areas of landscape research in China and foreign countries. However, when designing flower meadows, the blindness of species selection, the high cost of weed removal, and the poor sustainability of the landscape limited its application and promotion. In this context, the ecological CSR (Competition, Stress, Ruderality) theory was closely combined with flower meadow, and it was essential to prompting vegetation CSR adaptive strategy by exerting environmental pressure, reducing environmental disturbance and competitive intensity of dominant species to convert community to stress tolerance types, thus building rich species, less weeds and lower competition communities. Through many seeding experiments in Beijing area, based on different CSR strategies of plants, the paper provided suggestions from community structure, design models and etc., which supplied theoretical support and practical guidance for the species selection and application of flower meadows.
