红壤丘陵区不同类型生态系统的小气候效应

对浙江省金衢盆地红壤丘陵区雷竹Phyllostachys praecox,杉木Cunninghamia lanceolata,湿地松Pinus elliottii,湿地松 百喜草Paspalum notatum,杉木-湿地松,胡柚Citrus grandis 'Changshanhuyou',6种不同类型生态系统的小气候进行对比分析及灰色关联度分析.对比分析表明,杉木-湿地松林对土壤湿度和空气相对湿度的调节效果最佳,雷竹林对气温的调节能力最强;6种类型生态系统的关联度分别为0.781 6,0.738 4,0.823 4,0.759 5,0.712 2,0.741 8.对所选定的土壤湿度、空气相对湿度和气温3个因子而言,杉木-湿地松林的调节功能最好.图3表1参11

Study on microclimates of different ecosystems in hilly red soil areas

Comparative analysis and correlation analysis of microclimates in 6 ecosystems of Phyllostachys praecox, Cunninghamia lanceolata, Pinus elliottii and Paspalum notatum, Cunninghamia lanceolata and Pinus elliottii, Citrus grandis 'Changshanhuyou', in hilly red soil areas of Jinhua-Quzhou Basin, Zhejiang Province, were conducted. The results of comparative analysis showed that Cunninghamia lanceolata and Pinus elliottii was most effective to regulate the soil humidity, air relative humidity and Phyllostachys praecox was the most effective to regulate air temperature. The correlations of 6 ecosystems were 0.781 6, 0.738 4, 0.823 4, 0.759 5, 0.712 2 and (0.741 8) respectively. As far as the regulation of all three factors including soil humidity, air relative humidity and air temperature was concerned, Cunninghamia lanceolata and Pinus elliottii functioned the best.
