1Soil erosion along a long slope in the gentle hilly areas of black soil region in Northeast China显示文摘沿着在在在东北中国的黑土壤区域的轻轻的多山的区域的一个长斜坡的土壤侵蚀变化的特征被讨论。一个简化斜坡模型基于片断被用来分析在 Heshan 农场与不同斜坡长度在 10 个地阴谋上在 2003 和 2004 之间观察的流量数据和土壤侵蚀数据, Heilongjiang 省。我们发现土壤侵蚀在沿着斜坡或者改变的黑土壤区域在长斜坡上评价并且创造集中的侵蚀和星期侵蚀的其他的地区。每个地区的准确地方为不同降雨条件是不同的。在有更少和温和降水的一年里,小河不能发生在顶以内 50 m 在有大、集中的降水的一年里,小河能被形成从斜坡的顶甚至在 15 m 开始。CUI Ming CAI Qiangguo ZHU Axing FAN Haoming 2007Journal of Geographical Sciences2007,17,3:18
2Bottom Factors Applied to the Zoning Study of the Risk Levels of Landslides in the Three Gorges Reservoir Area显示文摘Without taking inducing factors into consideration, this paper adopts a quantitative analysis of the bottom factors in the Three Gorges Reservoir area, studies the relationship between the bottom factors and the development of landslides, and then zones the area according to risk levels. The bottom factors adopted in this paper include lithological characters(U_ 1 ), gradient(U_ 2 ), slope form(U_ 3 ), difference of height(U_ 4 ), and slope orientation(U_ 5 ). In 4 650 km 2 of the studied area, the areas of the very high, high, medium and low hazard degree area respectively were 57.94 km 2 , 2 305.15 km 2 , 1 241.6 km 2 , 1 045.31 km 2 . The methodological steps are ① inversion statistic analysis, ② the analysis of contribution ratio and weighing, ③ getting results via fuzzy evaluation of risk levels.QIAO Jianping ZHU Axing WU Caiyan TIAN Hongling 2006Wuhan University Journal of Natural Sciences2006,11,4:12
3A 3D visible evaluation of landslide risk degree under integration of GIS and artificial intelligence显示文摘Artificial intelligence has been used to obtain background factors (basic environmental factors) from landslide specialists. A 3D visible evaluation map may be charted by fuzzy evaluation, and the traditional plane map may be decoded into a 3D map by using factor weight from specialists system and technology of RS and GIS for quantitative sampling of these factors.QIAO Jianping, ZHU Axing, CHEN Yongbo& WANG Rongxun Institute of Mountain Hazards and Environment, Chinese Academy of Sciences and Ministry of Water Resources, Chengdu 610041, China Geography Department of Wisconsin University, Madison, Wisconsin, USA 2003Science China(Technological Sciences)2003,46,z1:6
4Soil property mapping by combining spatial distance information into the Soil Land Inference Model(SoLIM)显示文摘The Soil Land Inference Model(SoLIM) was primarily proposed by Zhu et al.(Zhu A X, Band L, Vertessy R, Dutton B. 1997. Derivation of soil properties using a soil land inference model(SoLIM). Soil Sci Soc Am J. 61: 523–533.) and was based on the Third Law of Geography. Based on the assumption that the soil property value at a location of interest will be more similar to that of a given soil sample when the environmental condition at the location of interest is more similar to that at the location from which the sample was taken, SoLIM estimates the soil property value of the location of interest using the soil property values of known samples weighted by the similarity between those samples and the location of interest in terms of an attribute domain of environmental conditions. However, the current SoLIM method ignores information about the spatial distances between the location of interest and those of the sample. In this study, we proposed a new method of soil property mapping, So LIM-IDW, which incorporates spatial distance information into the SoLIM method by means of inverse distance weighting(IDW). The proposed method is based on the assumption that the soil property value at a location of interest will be more similar to that of a known sample both when the environmental conditions are more similar and when the distance between the location of interest and the sample location is shorter. Our evaluation experiments on A-horizon soil organic matter mapping in two study areas with independent evaluation samples showed that the proposed SoLIM-IDW method can obtain lower prediction errors than the original SoLIM method, multiple linear regression, geographically weighted regression, and regression-kriging with the same modeling points. Future work mainly includes the determination of optimal power parameter values and the appropriate setting of the parameter under different application contexts.Chengzhi QIN Yiming AN Peng LIANG Axing ZHU Lin YANG 2021Pedosphere2021,31,4:3
5Mapping Detailed Soil Property Using Small Scale Soil Type Maps and Sparse Typical Samples显示文摘Soil type maps at the scale of 1︰1 000 000 are used extensively to provide soil spatial distribution information for soil erosion assessment and watershed management models in China.However,the soil property maps produced through conventional direct linking method usually suffer low accuracy as well as the lack of spatial details within a soil type polygon.This paper presents an effective method to produce detailed soil property map based on representative samples which were extracted from each polygon on the 1︰1000 000 soil type map.The representative sample of each polygon is defined as the location that can represent the largest area within the polygon.The representativeness of a candidate sample is determined by calculating the soil-forming environment condition similarities between the sample and other locations.Once the representative sample of each polygon has been chosen,the property values of the existing typical samples are assigned to the corresponding representative samples with the same soil type.Finally,based on these representative samples,the detailed soil property map could be produced by using existing digital soil mapping methods.The case study in XuanCheng City,Anhui Province of China,demonstrated the proposed method could produce soil property map at a higher level of spatial details and accuracy:1)The soil organic matter(SOM)map produced based on the representative samples can not only depict the detailed spatial distribution of SOM within a soil type polygon but also largely reduce the abrupt change of soil property at the boundaries of two adjacent polygons.2)The Root Mean Squared Error(RMSE)of the SOM map based on the representative samples is1.61,and it is 1.37 for the SOM map produced by using conventional direct linking method.Therefore,the proposed method is an effective approach to produce spatial detailed soil property map with higher accuracy for environment simulation models.ZHANG Shujie ZHU Axing LIU Wenliang LIU Jing YANG Lin 2013Chinese Geographical Science2013,23,6:2
