土地的面积

It is rich in natural resources,such as flat land resources,petroleum and natural gas resources buried underground and a vast area of reed,wetland and tideland.

辽河三角洲自然资源丰富，既有平坦的土地资源，地下还埋藏着丰富的石油和天然气资源，还有面积广阔的芦苇、湿地和滩涂资源，具有发展工农业生产的有利条件。

The new-born wetland out of the Fork Channel is situated in core area of YRDNR and should be paid high priority to protect its naturality and typicalness.

在保证保护区面积的总量平衡的前提下，通过对区域自然条件的分析，确定西区、南区两处分别为各162.5〓和148.6〓的土地作为农业开发的区域。

Based on a rather long temporal series of remote sensing data, employing RS and GIS as its tool and FVC that is of rather high sensitivity over the coverage of vegetation in arid area as its monitoring index of desertification, the dissertation analyzes the features of the dynamitic variation of desertification in Xinjiang over the years by using the slop variation to reflect the features of temporal-spatial distributing and the changes of areas of the desertification in Xinjiang.

以较长时间序列的遥感数据为基础，以RS和GIS为工具，选择了在干旱区对植被覆盖度上有较好敏感性的FVC的斜率作为荒漠化监测指标，利用1982~2000年期间新疆FVC斜率变化来反演新疆土地荒漠化的时空分布、面积变化，分析新疆荒漠化多年来动态变化特征； 3。

In the composition of tropical elements,the biggest proportions were held by Pantropical elements(16.5%) and Tropical Asian elements(12.2%).

同时也以10%的土地面积，拥有云南地区种子植物科数的77%，属数的55%和物种数的43%。

The enhancement of consumer's desire for good quality fruit (seedlessness, large fruit, high sugar content) and coming challenge after entering WTO also bring out citrus researchers new objectives.

消费者对于果品质量（如无核、大果、高含糖量等）要求的不断提高和土地面积的减小，以及中国加入世界贸易组织后中国柑橘种植业所面临的问题都给柑橘育种工作提出了新的研究课题。

From high resolution RS image of study area, gully head locations and land use information can be extracted, by performing overlay analysis on gully head locations map and flow accumulation map, slope gradient map, the slope and upslope drainage area of each gully head can be obtained.

采用的方法是RS技术与GIS技术相结合的方法，利用高分辨率卫星影像提取研究区内所有切沟的沟头位置和土地利用状况，将沟头位置与研究区的水流汇流网络图、坡度图作叠加分析，得到切沟沟头的坡度和上游汇水面积。

The 678-square-foot tomb hewn out of rock was discovered by a farmer plowing his field on the eastern edge of the ancient cemetery of Pella, some 370 miles north of Athens, archaeologists said.

从事挖掘工作的希腊考古学家称，这个面积达678平方英尺，在石头中开凿出来的墓穴是由当地一名农民在自己的土地上耕种时偶然发现的。

This also applies to the way the campaign maps have been drawn up, focusing not so much on large regions with a big city plonked in the middle, but on smaller areas, villages and towns.

同样，战略地图的绘制原则也转变为更注重细节：原版的&一大块土地中间摆着一个城市，周围点缀着几个小村子&的模式被舍弃了，代之以对乡村和城镇等面积较小地区的详细刻画。

The model adopts continuity equation, diffuse wave model, and the Mannings equation for surface runoff routing, while uses the Green and Ampt infiltration theory and Darcys Law for subsurface runoff treatment. Uncertainty analysis incorporating Monte Carlo simulation and a Maximum Likelihood Estimation and Efficiency Coefficient is used to retrieve optimal parameter values and to estimate the confidence interval for the simulation results.

目前已经完成模式中各相关模组的研发，包含利用DEMs 析取坡度、流向与集流面积；利用卫星影像评估土地利用类别；结合蒙地卡罗法、最大概似法与效率系数的参数率定器；以及整合Green and Ampt 的入渗理论、Manning 地表流速公式，Darey 定律和扩散波理论的水文演算模组。

Constructed rapid infiltration system is a new type of land treating technology which is based on the traditional rapid infiltration, because of better infiltration media replacing the natural soil, as a result, the hydraulic loading can be increased and the occupying land area can be minished.

人工土床快渗系统(Constructed Rapid Infiltration，简称CRI)为土地处理的一种类型，它是在传统快速渗滤系统(Rapid Infiltration，简称RI)的基础上发展起来的，其核心是采用渗透性能较好的渗滤介质代替天然土层，从而大大提高了水力负荷，减少了占地面积。
