牛山湖两种优势小型鱼类空间分布与沉水植被的关系! [PDF]
, 2012 运用8种网目规格的成套浮性刺网作为鱼类采样工具,于2005年夏季在长江中游浅水草型湖泊牛山湖进行鱼类定量采样,通过比较不同茂密程度黄丝草生境中的小型鱼类组成、数量和大小结构,探讨此类湖泊小型鱼类的空间分布特征及其与沉水植被的关系.采样期间共捕获13种1124尾鱼,依据其等级丰度和出现频次,和红鳍原!为该湖优势上层小型鱼类.在调查的沉水植物生物量范围内,鱼类物种丰富度和Shannon多样性指数与沉水植物生物量之间呈现倒抛物线关系;两种优势小型鱼类的种群丰度均与沉水植物生物量有着显著的线性正相关关系 ...

Haiyang yu huzhao赤潮暴发不仅会导致水体中积聚过量微藻细胞，还常常伴随出现氮磷等富营养化污染因子超标的问题。随着生态环境治理要求的提升，有害赤潮治理不仅需要高效除藻来控制灾害，还需要同时净化水体中的其他污染物质，对受污染水环境进行综合治理。该研究面向有害赤潮综合治理需求，以现有改性粘土法为基础，探究了在粘土中引入尿素合铁材料制备功能性赤潮治理材料的方法可行性，实验测试了新制备尿素合铁改性粘土(ferric carbamide complex-modified clay, FMC)的除藻降磷效果 ...

The impacts of habitat heterogeneity of mangroves on mollusks diversity at Dongzhaigang Bay, Hainan [PDF]
, 2016 包括软体动物在内的大型底栖动物是红树林生态系统的重要组成部分，几乎在所有的红树林生境类型中都能够发现它们的存在，其在红树林中占据了重要的生态位，通过穴居、取食等活动改变着红树林有机物循环的物理和化学过程，对红树林生态系统的结构和功能的维持具有非常重要的作用，是红树林生态系统中食物网的重要环节。本文选取了海南省东寨港国家级自然保护区内三个不同地点的红树林从空间尺度方面对其中的软体动物分布进行了研究。此外还比较了不同地点的红树植物群落内软体动物分布的特点。 选择了海南东寨港的湾口(塔市)、中部(后排 ...

Research on Optimization of Fe Clusters Structure Based on Structural Clustering Niche Differential Evolution Algorithm [PDF]
, 2016 团簇被称之为“物质第五态”。它是材料科学的新起点，在许多领域都有着广泛的应用。团簇的稳态结构对其独特的物理和化学等性质起到了至关重要的作用，因而受到许多学者的广泛关注。由于团簇的大小在几埃到几百埃之间，尺寸非常小，用实验设备很难合成和直接观测。因此用理论研究的方法来探究团簇的稳态结构显得十分重要。但是寻找团簇的稳态结构十分困难，除了基态结构之外，还存在成千上万的亚稳态结构。目前团簇优化问题已被学者证明为NP难问题，因此用传统的优化方法难以获得最优解，于是使得基于进化算法的全局优化方法得到了广泛应用 ...
