Special attention was paid to the corelationship of lan dscape pattern index and population proˉ portion. Results showed that the diversity and evenness of landscape p attern in Luoyang urban area were on a low level, none of the landscape types exhibited high domina nce,and the green land landscape was in better state.

结果表明，洛阳市区各个研究区景观多样性整体程度不高、分布均匀程度较低且由某种景观占绝对优势的现象较少，绿地景观整体较好；同时相关分析中，城市化率与各个景观格局指数间相关程度较低，其中与景观多样性、均匀度、优势度、破碎度均呈现出负相关性，而只和景观破碎度表现出一定的显著性。

The results show that as for the as-cast castings, eutectic Si particles are characterized as fibrous or long acicular shape as well as in homogenous distribution, and the impact absorbed energy varies from 1.17 to 2.35J. After T6 heat treatment, the eutectic Si particles become small granular or short bacilliform, and the aspect ratio and area fraction of Si particles decrease evidently. The energy of the T6-treated castings is 1.45-3.80 J, which is higher than that of the as-cast castings. Furthermore, the fracture mechanisms of different regions in the castings were analyzed and discussed.

结果表明：铸态下共晶Si粒子大多为纤维状或长针状，呈不均匀的网状分布，冲击吸收功在1.17~2.35J的范围内变化后；经T6热处理后，团簇状Al-Si共品相明显减少，共晶Si粒子呈现出粒状或短棒状，且细小均匀，Si粒子的长宽比和面积分数都有显著降低，冲击吸收功在1.45~3.80J的范围内变化，比铸态有明显提高。

After T6 heat treatment, the eutectic Si particles become small granular or short bacilliform, and the aspect ratio and area fraction of Si particles decrease evidently. The energy of the T6-treated castings is 1.453.80 J, which is higher than that of the as-cast castings. Furthermore, the fracture mechanisms of different regions in the castings were analyzed and discussed.

There were only 94 vascular plant species, belonging to 50 family and 75 genera. The dominant species in the communities were deciduous broadleaf species Liquidambar formosana, Robinia pseudoacacia, Ailanthus altissima, Acer buergerianum, and Celtis sinensis, evergreen broadleaf species Cinnamomum camphora and Elaeocarpus glabripetalus, and Phyllostachys heterocycla. Robinia pseudoacacia+Cinnamomum camphora community had the highest Shannon-Wiener index (1757) and Phyllostachys heterocycla+Acer buergerianum community had the highest Simpson index (0163), but no consistency was observed between the curves of H and D. For vertical structure, most communities had no significant understory stratification.

结果表明：辰山植物区系以泛热带和北温带占优势，具有典型亚热带和温带成分交汇和南北植物分布交错特征；但保育区内种类单一，维管束植物仅有49科69属94种；主要群落是以枫香、刺槐、臭椿、三角枫和朴树等为优势树种的落叶阔叶林，以香樟和秃瓣杜英等为优势树种的常绿阔叶林，以及毛竹林；物种多样性普遍较低，Shannon-Wiener多样性指数最高为刺槐+香樟群落（1.757），Simpson均匀度指数最高值为毛竹+三角枫群落（0.163）；多样性指数曲线和均匀度指数曲线不具有一致性的变化趋势；多数群落垂直结构中无明显林下分层现象；演替前期的落叶乔木种群后续个体不足。
