The canopy structure and leaf morphological characters of 4 sugarcane genotypes at different leaf layers on seedling were studied by using CI-100 plant canopy instrument and CI-203 area meter instrument. The results showed the leaf morphological parameters, canopy structure and radiation transmission at different leaf layers were notably different among different genotypes. The variation of Ila, Amfi, Dl at different leaf layers were mainly caused by the leaf width at relevant position. The variation of K at different leaf layers was related to Amfi and Dl. The variation of Td（transm. coef. for diffuse penetration）had significant correlations with Ila, Amfi and Dl. The variation of Tr（transm. coef. for radiation penetration）had significant correlations with Dl, leaf width and the ratio of leaf length to width. The variation of Par had significant correlations with Ila, leaf area, leaf width and the ratio of leaf length to width.

摘要利用CI-100数字植物冠层分析仪和CI-203叶面积分析仪测定了4个甘蔗品种不同叶位层的冠层参数和相应叶位叶片的形态特征，结果表明：不同基因型不同叶位层间叶片形态、冠层空间结构和冠层辐射特征存在显著差异，不同叶位层叶面积指数、叶簇倾角和叶分布的变化主要由冠层内不同叶位叶片叶宽的变化引起，而不同叶位层消光系数的变化主要与叶簇倾角和叶分布有关；散射光透过系数的变化主要与叶面积指数、叶簇倾角和叶分布有关，直射光透过系数的变化主要与叶分布、叶宽、长宽比有关，光合有效辐射的变化与叶面积指数、叶面积、叶宽、长宽比有关。

Micronucleus test results exhibited that significant differences in micronuclear rates were determined between 0.4 mL bone cement and 0.4 mL microsphere-coated bone cement groups and negative control group, but no significant difference was detected among other groups. This revealed that this microsphere-coated bone cement leaching liquor did not show significant cell heredity toxic effects. Nevertheless, microsphere-coated bone cement in the high concentration and high dosage groups exhibited low toxic effects, mainly showing increased hemolysis rate and micronuclear rate. Thus, it was necessary to control the dosage and concentration of microsphere-coated bone cement.

微核实验结果显示除0.4 mL骨水泥组和0.4 mL微球骨水泥组的微核率与阴性对照组差异有显著性意义，其余各组差异无显著性意义，说明该微球骨水泥的浸提液无明显细胞遗传毒性作用，但是高浓度和高剂量组的微球骨水泥仍有较低的毒性作用，主要表现为溶血率和微核率的提高，因此在应用时要适当控制微球骨水泥的剂量和浓度。

During the study period, we found that plants were present only in natural creek banks, but not altered ones. Comparisons between natural banks without plants and altered banks revealed no significant difference in both shrimp abundance and distribution. However, there was significant difference in shrimp abundance when natural banks with plants and altered banks were compared, suggesting that construction might have negative effects on plants and, in turm, on shrimp abudance. Comparisons between reproductive and non-reproductive season yielded significant results in both shrimp abundance and distribution, which resulted from the recruitment of juveniles to local populations.

在实验期间，自然河段有水蕴草而整治河段没有水蕴草的存在，比较无水蕴草的自然河段与整治河段，发现无论是数量或出现率都没有显著差异，然而，在有水蕴草存在的自然河段之多齿新米虾数量与出现率则较整治河段高，显示哈盆溪可能因为整治工程影响了底质的型态，导致水蕴草不易生长，进而影响多齿新米虾的数量及出现率；在季节方面，结果显示，不同季节在数量和出现率上都有显著差异，而此差异是因为幼虾在生殖季大量加入族群所致。
