摘要
滩涂,是国家重点资源开发区。因此,莱州湾生物资源已引起重视。但长期以来限于常规手段难以及时进行生产潜力的估价。本研究依据卫星遥感理论与技术,应用大地卫星MSS数据监督分类,将获取的地貌类型因子量值,配合生物定量采样相关因子参数,算得莱州湾主要经济贝类资源潜力。其资源量:文蛤(Meretrix meretrix)17505吨,四角蛤蜊(Mactra veneriformis)21886吨。这不仅具有经济意义,同时也有科学意义。
Tidal flat is one of the important resource development areas in China. Therefore, the biological resources of Laizhou Bay have attracted attention. However, it is difficult to estimate the production of tidal flat areas by using conventional methods. In this study, on the basis of the theory and technique of satellite remote sensing, using the supervised classification of the satellite MSS-CCT data, we calculated the potential resources of Laizhou Bay from the environmental factors of different geomorphic types and the factors associated with biological quantitative sampling. The results show that there are 17505 tons of Meretrix meretrix and 21886 tons of Mactra veneriformis, in this area, which is of important significance in both economy and sicence.
