It is suggested that mechanisms protecting epidermis of squamata species from UVB damage may involve in (1) Physical defensive mechanism: the death epidermal layer limited UVB transmitting to the viable cells;(2) Biochemical defensive mechanism: up-regulated CAT may protect skin from reactive oxygen species which may induced by UVB. Moreover, the lipid and proteins in the β-, meso- and α-layer may absorb incident UVB and formed damaged products that were limited in the original site;(3) Cellular defensive mechanism: quick initiating of proliferation of the germinal cells and forming of the new epidermis and shedding out the damaged epidermis shortened the damage process and restricted the damage area.

1物理性防御：角质层和中层阻挡绝大部分UVB透过，最大限度地减轻生发层的损伤；(2)生化性防御：通过上调CAT活性以减轻LVB诱导的活性氧对表皮的损伤，同时角质层蛋白质和中层脂类可吸收UVB，且形成的有害产物被局限于原位；(3)细胞性防御：通过迅速启动再生修复过程形成新的表皮，及时蜕去积累了脂类过氧化产物、受损蛋白质和晒斑细胞等的受损表皮，有效防止损伤的持续和蔓延。

Compared with the temperature of 15℃, the results showed that the RWC and the CAT activity decreased significantly, MDA and PRO content increased obviously under high temperatur, then cell membrane-lipid peroxided, membrane structure be destroyed, physiologic function disordered and resistance decreased, these were main reasons of tall fescue over summering hard and get ill easily.

结果表明：在高温下，以15℃为对照，RWC含量和CAT活性明显下降，MDA和PRO含量明显增加，导致细胞膜脂过氧化，膜结构被破坏，生理功能紊乱，抗性下降，这是其越夏困难、易发病的主要原因。
