In this thesis, beginning with the research of the Yellow River delta formation history, the landscape heterogeneity is related with the delta evolution. According to different dynamic environments, the Yellow River delta landscape is divided into three zones: delta plain landscape, tidal zone landscape and submerged delta landscape, and the landscape characters of each zone is analyzed and discussed respectively.

本文从黄河三角洲的形成和发育研究入手，将黄河三角洲的形成与演化与景观分异联系起来，根据动力因素的差异提出黄河三角洲景观的三带结构，即：陆上三角洲景观、潮间带景观和水下景观，就三个带的景观特征分别进行了比较深入的分析和探讨。

The deep water deposition means the deposition in the area where the water depth is larger than 30 meters, in which the major sediments are coarse sand and gravel. This kind of deposition is the relic deposition formed by the Pleistocene alluvial-lacustine deposition reworked under modern channel currents actions, and ususally the Holocene acummulation lack in the deep waters. The transitional zone deposition is the deposition between the low tidal level line and the 30 meters isobath, where the sediment types is changeable and the grain sizes are gradually coarsening from the low tidal line to the deep water area. This kind of deposition is developed by the deep water eroded sediments sorting under the transitional zone current action. The different types distributed along the isobath. The tidal flat deposition is the fine sediment deposition on the tidal flat which is flo sedimentation of the silty clay under the tidal flat dynamic action and ususally developed fluid mud on the lower tidal flat. The channel mouth deposition is the deposition in the channel mouth area. According to the sediment types, it includes sand deposition where there are coarse sediments supply and silt deposition where there are only fine sediments surpport.

峡道深水区沉积是指水深大于30米的峡道底部沉积，它以粗颗粒砂砾石沉积为特色，是现代峡道水动力对第四纪海退时发育的冲洪积和坡积物进行改造形成的蚀余沉积，全新世沉积地层往往缺失；峡道过渡带沉积是指水深介于低潮位线至30米水深线之间发育的峡道边坡沉积，该带沉积以沉积物类型多样为特色，自低潮位线至30米水深线，沉积物粒级逐渐变粗，由粉砂质粘土逐渐递变为中粗砂，是峡道深水区沉积物经多次分选沉积而发育的，基本平行于等深线分布的条带状沉积，在岸坡较陡岸段，过渡带下部可发育重力沉积；峡道潮滩沉积是指在低潮线与海岸线之间发育的细颗粒沉积，它是粘性细颗粒泥沙在潮滩动力作用下，发生动水絮凝沉积而形成的粉砂质粘土沉积，在低潮滩可发育浮泥；峡道口门区沉积则是在峡道汇入大海或海湾时，在峡道出口水流影响所及范围的沉积，根据峡道口门区供给泥沙的特性，峡道口门区沉积有粉砂质淤泥沉积和砂质沉积两种类型。

Based on the informative cluster analysis on succession of the plantation, the plant community in tidal zone can be classified into 4 categories: the primary types of plantation in succession is dominated by Saltliving Wormwood ; the climax in which Lalang Grass is the dominant, the seral community in which Chinese Aeluropus is the dominant; and the marsh community where reed is prevail.

通过信息聚类分析方法对滩涂的植物群落进行研究表明：滩涂植物群落可分为四种类型：以盐蒿为代表的演替初级阶段类型；以白茅为代表的演替高级阶段类型；以獐毛为代表的演替过渡阶段类型；以及以芦苇为代表的沼生植物类型。

In an evaluation of habitat values, it shows that the quality of habitats with plantation of Chinese Aeluropus in tidal zone, Saltliving wormwood beaches, tidal lands with plantation of Lalang Grass are the best; the habitat with plantation of reed beds, the bald beach, the aquicultural ponds as well as the salt works are acceptable habitats; the quality of agricultural fields is obviously bad valued.

丹顶鹤生境状况的生境模糊综合评价结果表明：獐毛草滩，盐蒿滩和白茅草滩的生境质量为良，芦苇地，光滩，水产品养殖塘和盐田的生境质量为一般，而农业生产用地的质量为差。

Sponge is one of the most primitive multicellular animals in the world, which distributes widely on earth, from tidal zone to deep sea-bed, even can be seen in fresh water.

海绵是世界上最原始的低等多细胞动物之一，广泛分布于地球上的各种水体，由潮间带到深海海底，甚至淡水中都可见到。

ABSTRACT The Yellow River delta located in the land and sea interaction zone and is being formed with the coaction of the River and Bohai sea. The three parts of the whole delta, i. e. the delta plain, tidal zone and submerged delta, are in different dynamic environments. The delta plain is controlled by the land surface processes. The tidal zone is under the coaction of the river and the sea.

黄河三角洲处于海陆交错地带，是河流与海洋因素共同作用的堆积体，从陆上三角洲平原到潮间带直至水下三角洲受不同动力因素的作用，陆上三角洲平原主要受陆地表层过程的影响；潮间带受陆、海动力的共同作用，而水下三角洲主要受海洋动力的作用。

Shoaly land is a very important land and space resource with vast uses. Among shoaly land, the legal character of supra tidal and tidal zone is land, and it's ownership belongs to the country or peasant collective, but the legal nature of sub littoral zone is sea, so it's ownership only belongs to the country. And the ownership of shoaly land which silt up naturally should be determined according to the attaching rule.

沿海滩涂是一种重要的土地资源和空间资源，其中潮上带和潮间带的法律性质是土地，所有权可以属于国家，也可以属于农民集体；潮下带部分本质上属于海域，所有权只能属于国家；自然淤积形成的滩涂所有权归属应该按附合规则确定。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
