摘　　要：采用系统调查的方法,对惠州市惠阳永湖百利宏荔枝园不同害虫治理模式下杂草群落进行研究。结果表明,与自然区相比,对害虫进行化学防治的化防区内杂草群落结构未发生显著变化。化防区杂草有14个科23个种,自然区有14个科22个种,且2个区的多样性指数和均匀度指数基本一致,但其优势种有所不同。化防区的优势种有酢浆草(Oxalis orniculata L.)、芫荽(Coriandrum sativum Linn.)和繁缕(Stellaria monosperma Buch.-Ham.ex D.Don);而自然区的优势种为酢浆草(Oxalis orniculata L.)、扛板归(Polygonum perfoliatum L.)和少花龙葵(Solanum photeinocarpum Nakamura)。Through systemic investigation, a study has been conducted to investigate the structure of weed community under different pest control methods at Bailihong Litchi Orchard in Yonghu, Hui Yang. The findings showed that no significant impact was found on the structure of weed community in the chemical control area where chemicals were used to control the breeding of pests. There were 14 families, 23 species in the chemical control area, while in the natural area there werel4 families, 22 species. The diversity index and the evenness index in two areas were the same, but the dominant species were different. There were six dominant species in the chemical control area, including Oxalis orniculata L., Coriandrum sativum Linn and Stellaria monosperma Buch.- Ham. ex D. Don . There were only two dominant species in the natural area, which were Oxalis orniculata L., Polygonum perfaoliatum L. and Solanum photeinocarpum Nakamura.
