摘要: 首先对分形理论在生态学中的应用情况作了简要介绍,然后应用它对梅子垭水库的藻类叶绿素a浓度场水平2维空间格局进行了分析,通过对不同时间各浓度轮廓线的空间占据能力进行比较分析,确定了各浓度的稳定程度。可由此说明浮游植物的变化情况和生长潜力。

Abstract: The development of fractal theory and its applicati on in ecology is reviewed in the paper, following with the analysis of horizonta l two-dimension spatial pattern of concentration field of algea chlorophyll-a in Meiziya Reservoir. Thro After the comparison and analysis of spstaial occu pancy potential of various concentration contours in different time, The authors determine that the concentration is of steady presence which can decide phytopla nkton's growth and change potential.
