查询词典 correlation analysis

The correlation among all these parameters of four different types of wear debris is conducted.

Based on connotation of intensive land use and the evaluation principle of intensive deployment of city land,this paper establishes a set of scientific and practical index system in evaluating the intensive utilization of city land,and conducts a demonstration analysis in 13 cities of Jiangsu Province by the way of multifactor comprehensive evaluation,rank correlation coefficient and cluster analysis.During the last ten years from 1997 to 2006,the urban land use intensity had increased in all cites,but varied in amplitude and mode in different cities.Urban land use intensity was descending sharply from the southern and the middle to the northern part of Jiangsu Province,in which Nanjing was the tiptop and Suqian was the lowest .

从城市土地集约利用的内涵入手，依据城市土地集约利用评价的原则，从土地利用投入水平、土地利用程度、土地利用效率、土地利用生态环境质量等方面构建了一个具有三级层次结构的城市土地集约利用度评价的指标体系，并在此基础上采用多因素综合评价，秩相关系数和聚类分析的方法以江苏省13个地级市为例进行了实证分析，结果表明：（1）1997～2006年，江苏省13城市土地利用集约度都得到了提高，但是提高的幅度和方式不同；（2）不同城市，苏南、苏中和苏北之间城市土地利用集约度呈现出明显的城市和地域差异，其中，省会南京最高，苏北的宿迁最低。

On the base of the advanced theories, research methods from home and abroad, intensive use of urban land on the connotation and extension have been defined, also the driving factors of intensive use land in Xinjiang have been analyzed. As the case of nineteen cities of the Xinjiang Uygur Autonomous Region, from the land input level, the extent of land use, land-use efficiency and land use in four areas of eco-environmental quality, the establishment of a level of intensive use of urban land evaluation system has been done in this ***. Using the methods of Principal component analysis, Spearman rank correlation coefficient and ArcGIS, calculate the principal city of the intensive use of urban land points between 2001-2006, the municipalities of urban Land Use Composite Index, build the three-dimensional display model of Intensive use level of urban land, then analyses the characteristics of spatial-temporal variance of the urban land intensively utilization. Finally, analysis propose measures and advices.

本文反在呼取海外外相闭实际和研讨方式的基本上，闭于城市土地集约当用的外涵及外延入行了界订，并闭于旧疆土地集约当用的驱动果荤入行了剖析，然后以旧疆19个从要城市为研讨区域，自土地投入火平、土地当用火平、土地当用效力和土地当用生态环境量量四个方里，树立了城市土地集约当用火平评价指本体解，采取从败开剖析法闭于旧疆2001—2006暮年城市土地集约当用火平入行了评价，盘算各从要市的城市土地集约当用得开，用秩相闭解数闭于所盘算出的各市的城市土地集约当用综开得开入行时光特征剖析；还帮ArcGIS软件，剖析旧疆城市土地集约当用火平的空间格局；自城市非工业己口、投入、产出取用地删加弹性三个方里剖析城市土地分体集约当用收铺趋背；最初降出了土地集约当用的闭于策建议。

Variance analysis and rank correlation were used for statistical analysis.

Multiple linear regression equation between LST and brightness temperatures of AVHRR channels 4 and 5 was almost at the significant level (p＜0.05), and the level was not improved by adding brightness temperature of AVHRR channel 3 as a regressor. Path analysis is a statistical technique that partitions correlations into direct and indirect effects, and differentiates between correlation and causation. The results of path analysis showed that the direct effects and indirect effects of brightness temperatures of AVHRR channels 4 and 5 to LST were strong, respectively, the direct effect and indirect effects of brightness temperature of AVHRR channels 3 to LST were weak. These implied the brightness temperatures AVHRR channels 4 and 5 should be involved in retrieving LST.

多元线性回归分析结果表明，土地表面温度与AVHRR第4、5波段亮度温度间的回归方程接近5％的显著水平；通径分析的结果表明，AVHRR第4、5波段的亮度温度对土地表面温度的直接作用和间接作用均较强，而AVHRR第3波段的亮度温度对土地表面温度的直接作用和间接作用均较弱，因此，在反演土地表面温度时必须同时考虑AVHRR第4、5波段的亮度温度。
