Examples
- The discussion on models for estimating soil erosion rates from caesium - 137 measurements on cultivated land
示踪农耕地土壤侵蚀速率模型的比较研究 - Rains have been poor , and the government ' s disastrous land - reform programme has turned once flourishing commercial farming into subsistence agriculture
雨水非常稀少，并且政府实行的糟糕的土地改革项目也将曾一时繁荣的经济农场成为仅能维持生存的农耕地。 - Compared with jiang ' s regressive model , the soil rates by 137cs tracer is lower about 10 % than that by jiang ' s regressive mode when they has been used to estimate rates of soil loss on runoff plots
因此，在利用~ ( 137 ) cs技术示踪农耕地土壤侵蚀速率时，这四个模型各自计算的土壤侵蚀速率差异较小。在估算径流小区土壤侵蚀速率中各模型与江忠善经验回归模型的结果相差都在10左右。 - For the cultivated study field , the 137cs concentration is relatively uniform within the plough layer . 2 . the difference and sameness among the existing l37cs models have been discussed , and their precision have been validated by comparing with the regressive model of soil erosion
分析了~ ( 137 ) cs示踪农耕地土壤侵蚀速率模型间的异同，并以土壤侵蚀的经验回归模型为参照对~ ( 137 ) cs法计算的土壤侵蚀速率进行验证。 - The paper deals with the main problems of the land resource in sichuan province : both the predominant land form types and the high quality land types make up little share ; not only the photo - temperature productivity but also the land potential productivity need raising ; the quantity of cultivated land , forest land and grazing land averaged to great population is lacking , which indicates that the contradiction between man and land is outstanding ; on the one hand the reserved land resource suitable for cultivation is insufficient , on the other hand the land difficult to cultivate accounts for great share ; the level of land exploitation and utilization is low and the land productivity develops slowly
四川土地资源的主要问题是优势地貌类型占有量少；优质地类比重不大、光温潜力和土地生产潜力的发挥不够；人多地少，人均耕地、林地和牧草地不足，各地类人均占有量极低，人地矛盾十分突出；宜农耕地后备资源贫乏，难利用土地比重大；土地开发利用程度低，土地生产力水平发挥不够。
