摘要/Abstract

摘要： 依据草地对放牧的生理响应,用牧草生理低限(PLL)、生理上限(PUL)和再生长期(R期)长度/放牧期(G期)长度的比值(R/G)等指标,构建了放牧草地健康评价的生理阈限双因子法,并以光合作用及其相关参数分析了多年生黑麦草轮牧草地的健康指标.维持草地适宜的双因子生理阈限和R/G比值,旨在放牧后草地功能与健康的完全恢复,是放牧草地可持续经营的目标.

关键词: 放牧草地, 健康评价, 生理阈限双因子法

Abstract: Evaluation of the function and health of grazed grassland is an important aspect of grazing ecology.Based on analyzing the physiological response of grassland to grazing,a double factor method of physiological threshold was developed.Physiological low limit (PLL),physiological ultimate limit (PUL), and duration ratio of regrowth to grazing stage (R/Gratio) were feasible to evaluate the sustainable management on the function and health of grazed grasslands. The reasonable threshold values of PLL, PULand R/Gratio could play an important role on the complete recovery of the function and health of grassland after grazing, which was the goal of sustainable management of grassland ecosystems.

Key words: Grazed grassland, Health evaluation, Double factor method of physiological threshold
