| 3. | On the basis of the references , the authors introduced the approach of blurry evaluation into the classification of soil erosion in the urban area 将模糊评判处理方法引入浙江省土壤侵蚀强度等级的确定。 |
| 4. | The results indicate that the spatial pattern of soil erosion is related to the slope land shape . it has clear vertical and horizontal distribution features 研究表明,坡耕地土壤侵蚀强度的空间分布与地形因素密切相关,具有明显的垂直分布特征和水平分布特征。 |
| 5. | Gis technique was used in the soil erosion zoning . the model for soil and water conservation for different zones was proposed , and the corresponding method for soil erosion control was analyzed . the main results are as follows : 1 将地理信息系统技术用于土壤侵蚀强度分级及类型分区中,对克拉玛依市水土保持进行了分区,提出了不同分区的水土保持治理模式,并制定了城市水土流失治理方向。 |
| 6. | The soil erosion has become more and more intensive horizontally from the ridge to the center of the shallow gully . the soil erosion intensifies , and then weakens vertically from the divide to the edge of the gully 在水平方向上,由浅沟分水脊经浅沟沟坡到浅沟中心, 7be和’ 37cs复合示踪坡耕地土壤侵蚀产沙的空间分布特征土壤侵蚀强度逐渐增强;在垂直方向上,从分水岭到沟缘线土壤侵蚀强度呈先加强后减弱的趋势。 |
| 7. | A quantitative method of rs for monitoring soil losses based on gis and the formula and algorithm of each model factor about the revised universal soil loss equation ( rusle ) are described in this paper , the spatial distribution law of soil erosion is discussed and the amount of soil loss of the small watershed is predicted running the model of rusle by the support of gis 摘要以三峡库区典型小流域为研究区域,通过遥感和野外调查进行信息采集,建立了流域环境数据库;在gis支持下,根据修正通用土壤流失方程( rusle )模型对数据库实施运算操作,探讨了流域内土壤侵蚀强度的空间分布规律,并估算了小流域水土流失量。 |
| 8. | The outcomes show that the sequence of soil erosion of types of land use in different regions is different and the sequence of soil erosion of types of land use in different periods of the same regions is uncertainty ; the occurred rate of soil erosion of new wasteland is higher than that of idle wasteland for years ; the occurred rate of soil erosion of grassland is higher ; the occurred rate of soil erosion of non - irrigated farmland is high and the soil erosion intensity of land used for construction is great during construction and becomes smaller after completion 结果表明:不同区域土地利用类型的土壤侵蚀序列各不相同,而同一区域不同时期土地利用类型的土壤侵蚀序列不确定;新出现的难利用地比长期闲置的难利用地土壤侵蚀发生率高;草地土壤侵蚀发生率偏高;耕地中旱地的土壤侵蚀发生率高;建设用地建设时土壤侵蚀强度大,而建成后土壤侵蚀强度小。 |
| 9. | The paper introduces and amends the composite indexes of soil erosion intensity and regional soil erosion intensity and conducts quantitative analysis on spatial relationship of types of land use and soil erosion intensity of whole china territory , the middle and lower areas of liaohe river , headwater area of danjiangkou reservoir of south - north water transfer project of hubei part and 4 regions of huidong county in guangdong based on sum up of general study methods of spatial relationship of land use and soil erosion 摘要在总结土地利用与土壤侵蚀空间关系一般研究方法的基础上,引入并修正了土壤侵蚀强度综合指数和区域土壤侵蚀强度综合指数,时整个中国境内、辽河中下游地区、南水北调丹江口水库水源区湖北部分和广东省惠东县4个区域土地利用类型与土壤侵蚀强度空间关系进行了定量比较分析。 |
| 10. | According to the current situations of soil water erosion in city keramay , factors affecting soil erosion loss were analyzed , soil erosion intensity was graded and the soil erosion type was divided into several zones . specially , the water and wind erosion features were analyzed and the features were considered as the major factor for division of soil erosion type 论文从克拉玛依市水土流失现状入手,通过重点分析影响水土流失的几个重要因素,对当地土壤侵蚀强度进行了分级及对土壤侵蚀类型进行了分区,特别对水力风力交错侵蚀特征进行了分析,并以水力风力侵蚀特征作为土壤侵蚀类型分区的主要依据。 |
