The stem flow of spruce and larch had acidulation on the soil, but the soil around the bole of spruce didn't present intensive acidity (the lowest pH of water and KCl immersion were 5.13 and 4.79, respectively), so the acidulation of stem flow is not the direct reason of spruce death.

虽然两树种树干径流对土壤均产生了酸化作用，但由于云杉树干周围土壤PH并没有出现较强的酸性（水浸pH下降到5.13，盐浸pH下降到4.79），因此，还不能认为云杉的衰退死亡与树干径流的酸化作用有直接关系。

According to the change of the enemy\'s quantity and the qualitative theory of the differential equation, we research the spruce aphides and its predator system. At the same time, we discussion the spruce aphid multiplication model when the natural enemy quantity is a certain value and the periodic oscillating model whose the quantity of the natural enemy changes along with the time. Obtains the stability condition of the balance point and the limit-cycle existing condition, the system presents the dissipative structure\'s character. Finally it explains that this theoretical analysis has certain practical significance regarding the preventing and controlling harmful insect.

第五章，松毛虫与其天敌的关系是食饵和捕食者的关系，根据天敌数量的变化，利用微分方程定性理论，研究松毛虫与天敌系统，讨论天敌数量为一定时的松毛虫增殖模型和天敌数量随时间变化的周期振荡模型，得到正平衡点全局稳定性和极限环的存在条件，通过计算机模拟，说明周期振荡的捕食模型能够呈现典型的时间耗散结构特征，对于防治害虫有一定的实际意义。
