1.The wetland acreage in 2000 is only 1/4 as much as that in 1954. While arable land acreage increased from 223 173.54 hm2 to 597156.25 hm2. The acreage percentage increased from 25.31% to 70.45%.
而耕地面积由223 173．54hm2增加到597 156．25hm2,由占总面积的25．31％增加到70．45％。
2.The degree of visual interest to the ROI of the image is regarded approximately to be an inverse measure of the acreage of the ROI. As the acreage of the ROI is zero, the method will become the objective quality assessment of image, that is to say, the objective quality assessment of image is a specific case of the method in this paper.
该方法近似地认为人眼对感兴趣区的兴趣程度与其面积成反比 ,当图象中感兴趣区的面积为零时 ,该文方法将退化为客观质量评价方法 ,也就是说客观质量评价方法是该方法的特例 .
3.③Social-fixed-asset investment correlated significantly positively to construction land using acreage in Chongqing, the coupling equation is y=0.0051x+47.286(y denote construction land acreage,x denote social-fixed-asset investment);
③重庆市固定资产投资与建设用地面积之间相关性达极显著水平,其耦合关系模型表现为y=0.0051x+47.286(y为建设用地面积,x为固定资产投资);
4.The planting acreage and yield of winter Chinese date in Cangzhou region were analysed in instances by using the model of GM(1,1) by MATLAB language according to the original data of the winter date in Cangzhou from 2000-2004. The planting acreage and yield in 2005 are forecasted by this model with provides scientific advice to correlative departments for proper decision-making.
采用灰色理论中的GM (1,1)模型,用MATLAB语言编程,以沧州2 0 0 0～2 0 0 4年冬枣种植业的有关原始数据,对该地区冬枣种植面积和产量进行了实例分析、检验。 进而用该模型预测出2 0 0 5年沧州冬枣的种植面积和产量,为有关部门正确决策提供了科学依据。

8.According to this experiment, there are 100m2 of rain-harvesting acreage, then 3m3 rain harvesting pool will be builtcorrespondingly in gneiss area of Tai-hang mountain.
根据本试验研究，在太行山片麻岩区，每100m~2的集雨面积对应修建容积为3m~3的集雨池，便能取得较好的集雨效果。
9.We use the landscape acreage index, landscape fragmentation index, landscape apartness index, landscape diversity index, landscape dominance index, landscape evenness index and landscape shape index, to analyze the characteristics of the changes of landscape based on the landscape structure in 1996 and 2004.
研究过程中主要以1996年和2004年土地利用景观格局为基础，采用景观类型面积指数、景观破碎度、景观分离度、景观多样性指数、景观优势度、景观均匀度、景观形状指数分析区域土地利用景观格局变化特点。
10.Dagangshan hydroelectric power station is one of the main large-scale hydroelectric projects build on Dadu River. The acreage of controlling watershed around dam site reaches to 6.27×10~4 km~2,which is 81% of the whole watershed. The average flux for many years is 1000mVs and the normal water level is 1130m as planned.
大岗山水电站是大渡河干流近期开发的大型水电工程之一，坝址处控制流域面积达6.27万km~2，占全流域的81％，多年平均流量约1000m~3／s，电站初拟正常蓄水位1130m，大坝壅水高度180m～190m，最大坝高约210m，总库容约7.42亿m~3，电站装机容量2400MW。
