摘要
本文概述了神府煤田在柳塔镇辖区内的土壤类型及其分布和土壤的基本理化性质。并应用模糊综合指数法对区内土壤养分状况进行评价，表明河谷川道区及部分沟底地土壤养分充足；而盖沙丘陵区的长期耕种和培肥的土壤养分充足，但是不便于培肥的农地土壤以及稀疏草地土壤养分缺乏。根据养分的测定值及养分的模糊综合评价结果，提出了培肥土壤和提高土壤有效养分途径。
The soil types,their distribution and their basic properties were presented. The soil nutrient levels were evaluated by means of the fuzzy comprehensive index (FCI). The results showed that the nutrient level of the soils in valley and the bottom of some gullies is higher.In the sand hilly region,the nutrient level of some soils is higher because of the long-term fertilization,but the nutrient level of both the soils inconveniently fertilized and the soil in sparse grass land is lower. Based on the soil nutrient contents and the results of evaluation,some ways are given to fertilize the soil and raise the available nutrients.
