| 中文摘要 | 本文在河西走廊临泽样区已在研究的工作基础上，根据土壤基层分类单元-土系划分的理论和方法，对河西走廊临泽样区土系的应用进行了初步的探讨和研究。利用研究区各土系的相关资料，初步建立起土系属性数据库系统；并以河西走廊临泽样区为例，选择建立了数学模型：P = k·Q·T·S初步探讨了绿洲农区土壤生产潜力问题，得出临泽样区各耕地土系土壤生产潜力状况为：兰家堡系、倪家下营系的土壤生产潜力高，分别为7085.90kg/hm~2，6323.98 kg/hm~2，曹家庄系、盘石营系、东三村系、化音系和五三村系的土壤生产潜力最低，分别为3733.43 kg/hm~2，2438.24 kg/hm~2，3504.97kg/hm~2，3123.89kg/hm~2和2666.74 kg/hm~2。并把样区耕地土系土壤分为以下两个等级：高潜力地，包括兰家堡系、倪家下营系两土系；低潜力地，包括曹家庄系、盘石营系、东三村系、化音系、五三村系等土系。根据样区绿洲农区三个农业生态区中三种不同土地利用方式，即城郊型土地利用方式、温和型土地利用方式和温凉型土地利用方式为评价单元，对临泽样区土系在土地可持续利用方面进行了初步探讨。同时，进一步提出样区土地持续利用的途径：（1）遵循生态规律，以生态系统健康发展为原则。（2）土地资源的开发与保护并重，严格控制人口，加强耕地的保护。（3）合理规划，以水定地。（4）增施有机肥料，以改善土壤理化性能。 |
| 英文摘要 | Along with the advance in the soil classification, the development of soil classification from qualitative description to quantitative analysis is being deepened step by step. It is a basis of soil survey and mapping, and of transferring agricultural technology. And it is also a medium of soil information exchange. The knowledge in soil science is forever advancing so should be our soil classification system. Based on the diagnostic horizons and diagnostic characteristics, with soil classification theory as guide, the work on the application of soil series of Linze zone in the Hexi corridor is studied in the paper as follows: 1. According to the obtained data mainly on the 12 soil series profiles, relating the study area in the Hexi Corridor, the author attempts to establish the attributive database of soil series. 2. Meanwhile, through analyzing comprehensively the factors and the accumulated information on soil resources of the study area in the Hexi Corridor, the potential productivity of soil resources to agriculture is also inquired in oasis area. Based on the mathematical model: P = k·Q·T·S we have obtained the following results: the suitable soil area to agriculture with high potential accounts for 27.33%, including Lan jia-bao soil series and Ni jia-xia-ying soil series and the suitable soil area to agriculture with low potential accounts for 6.21%, including Dong san-cun soil series, Pan shi-ying soil series, Hua yin soil series, Cao jia-zhuang soil series and Wu san-cun soil series. The soil areas are 8936.582hm~2 and 2483.251 hm~2 respectively. 3. In the end, the controlling measures of soil improvement and index systemy of sustainabale land use envaluation in the Linze zone are raised in this paper, in the light of reasons and analyses of arable soil series suitable to agriculture of the study area. |
