During the first part, investigate the numbers and location of the different nature reserve, and review about its development, discuss the cause about the rapid developmeng about the protection areas of nature around Beijing. During the second part, this paper use the Geographical Information System to analyze the different sight function, plot our distinct function about the protection area of nature around Beijing. In the third part of this paper, the ecology function was special analyzed. This paper picked up several factor about the ecology and establish mathematics model to detect the most rational ecology distribution, bring forward the new constructive, wilder constructive and combination project. In the last parts of the paper, this paper use the Geographical Information System to analyze the different brim about the protection area of nature around Beijing, calculating the p/a and figure coefficient, and bring forward the brim theory for the nature reserve and city system.

在数量布局方面，包括北京周边各个不同级别的保护区的数目、位置分配布局和发展趋势研究，探讨北京市周边自然保护区数目和面积在99年和2000年突然增长的主要原因，以及今后北京自然保护区的发展方向；在景观布局方面，主要根据不同自然保护区的空间和功能的不同，计算延庆县各个自然保护区的景观多样性指数和景观优势度指数，并结合地理信息系统和航片，划分出不同的景观功能区间，以及各个功能区间之间的相互关系；在生态布局方面，综合考察北京周边自然状况，提取多项因子，建立评价模型，计算出各项因子权重，从而对其自然保护区的生态功能布局的合理性进行评价和趋势分析，为本文提出北京市周边自然保护区新建、扩建与合并的方案提供依据；在边缘布局方面，利用边缘效应理论和研究方法，创新提出&边缘类型样块分析法&，提取多个样方并结合地理信息系统，计算p/a比和自然保护区边缘的形状系数，划出自然保护区边缘效应趋势变化图，考察北京周边自然保护区的边缘效应，以及对城市的生态边缘功能。

In the process of constructing the EDRI, we define the entropy weight on the basis of the theory of information entropy, and the synthetic weight of evaluating indicators, which is more rational for the model, is determined by combining the entropy weight with the expert's subjective weight.

在地震灾害风险指数的建立过程中，根据信息熵理论计算熵权，采用熵权与专家意见相结合的方法确定风险指数的综合权重，从而使模型权重的确定更加合理。

For any level, based on the evaluated indices of previous level (for the lowest one,based on the normalized data),combining the incomplete weight information of the lev...

对于任意一层指标，以前一级的评价指数为基础，结合该层指标权重的不完全信息，建立只有输出指标且含有偏好信息的数据包络分析模型，求出平均交叉效率，并将其作为该层的评价指数。

For any level, based on the evaluated indices of previous level (for the lowest one, based on the normalized data), combining the incomplete weight information of the level, a DEA model with output only and preference information is was produced, and then mean cross-efficiencies were calculated.

对于任意一层指标，以前一级的评价指数为基础，结合该层指标权重的不完全信息，建立只有输出指标且含有偏好信息的数据包络分析模型，求出平均交叉效率，并将其作为该层的评价指数。

The All Farm Index and All Crop Index are at record highs.

农产品指数和作物指数均达到纪录最高水平。

We used GIS got sum planting area, used GVG got crop planting index.

在本次研究中，我们利用3S技术，选择合适的TM遥感数字图像，建立了目视解译标志，在高性能计算机平台上经人机交互解译，应用GIS软件提取耕地总面积，由GVG软件获得作物种植面积指数，应用耕地总面积种植指数完成各个不同作物的种植面积的提取，取得了满意的结果。

This paper, by establishing some functions between theoretic unit production of standard crop and natural quality of farmland graduation, and between feasible unit production of standard crop and utilization index, verifies the theoretic unit production, feasible unit production, and based on this, the regional theoretic unit production, regional feasible unit production.

通过建立农用地分等单元标准粮理论单产和自然质量等指数的函数关系、标准粮可实现单产和利用等指数的函数关系，分别核算分等单元的理论单产及可实现单产，以此为基础核算区域理论产能及可实现产能。

Comparing with traditional cultivation system (two seasons planting cucumber with fallowing in summer), planting leafy vegetable anti garlic in summer increased the yields of the two crops anti the soil microbial biomass carbon content, total microbial population, and sucrase activity, decreased the amounts of soil nematode and root-knot nematode, and maintained a relative high Shannon-Weaver index. Planting crown daisy, garlic, and spinach in summer increased soil sucrase activity by 8.9%, 89.5%, and 36.9%, and the planting of crown daisy and garlic also increased the Shannon-Weaver index by 7.7% and 9.4%, respectively.

结果表明：夏茬休闲期种植速生叶菜和青蒜增加了土壤微生物量碳含量、微生物总量和蔗糖酶活性，维持了较高的Shannon-Weaver指数，减少了线虫和根结线虫的数量，增加了各茬作物产量，夏茬种植茼蒿、菠菜、青蒜后土壤蔗糖酶活性分别增加了8.9%、36.9%和89.5%，夏茬种植茼蒿和青蒜后Shannon-Weaver指数分别提高了7.7%和9.4%。

Because China's economic present is almost as murky as its future, the Board also released a monthly "coincident" index, which provides a gauge of current activity. This index, based on indicators from electricity generation to passenger traffic, is more timely than the official GDP figure.

由于中国目前的经济几乎与未来的经济一样难以琢磨，世界大企业联合会还发布了提供当前活动情况的月度&巧合&指数，这个指数基于从发电到公共交通的参数比官方的国内生产总值数据更加及时。

The research about species diversity of desert plant shows that diversity index is higher in co-dominant community.

通过对荒漠植物群落物种多样性特征研究表明，共优种群落的物种多样性指数较单优种群落的物种多样性指数高。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
