摘要
根据2005年、2007年对黄河三角洲米草分布面积的调查,测算了米草的扩展速度;分析、测定了米草分布区的主要生态因子,研究了其对米草扩散的影响.结果表明:气温、水温、潮汐、盐度、水质与底质等主要生态因子均有利于米草的生长和扩散,灾害性气候因子对米草的扩散影响不大.
Based on the investigation of Spartina spp. distributed area in Yellow River Delta,the expanding speed of Spartina spp. was measured. In Spartina spp. distributed area,the main ecological factors were analyzed and measured. The effect of those ecological factors on the Spartina spp. expanding was studied. Results showed that air and water temperature,tide, salinity and the quality of water and sludge all had influences on the growth and the expanding of Spartina spp. The harmful climatic factors had little effect on the expanding of Spartina spp.
