从生态及解剖的角度，研究制革污泥对杉木（Ｃｕｎｎｉｎｇｈａｍｉａｌａｎｃｅｏｌａｔａ）木材结构及周围环境的影响，结果表明：施用制革污泥的杉木的生长轮比未施制革污泥的杉木生长轮宽，心材颜色深，早材管胞的长度、弦向直径、射线频率和高度、壁的厚度均比未施制革污泥的杉木相应值高，制革污泥使杉木木材组成分子的数量特征值增加，这说明制革污泥促进了杉木的生长，使其生长最快时期提前３～４年，缩短了主伐周期，促进了具有较强吸收铬的能力的凤尾蕨的生长，且改变了周围的环境。制革污泥是工业废弃物，它可作为杉木的一种肥料，为利用制革污泥提供了一种生物解决方法。
From the perspective of ecology and anatomy, the effect of tannery sludge on the wood structure and surrounding environment of Cunninghamia lanceolata was studied. The results showed that the growth of Chinese fir with tannery sludge was larger than that of Chinese fir without Clay , The color of heartwood is dark, the length, chordwise diameter, ray frequency and height of early plume, wall thickness are higher than the corresponding values of non-leather-coated Chinese fir, and the quantity of chalcopyrite Value increased, indicating that the leather sludge to promote the growth of fir, the fastest growing period of 3 to 4 years ahead of schedule, shortening the cutting cycle, promote the ability to have a stronger absorption of chromium growth and change Pteridaule The surrounding environment. Tannery sludge is an industrial waste that can be used as a fertilizer for fir and provides a biological solution to the use of tannery sludge.
