空心村土壤肥力质量分析及评价

Analysis and Assessment of Soil Fertility Quality in Hollowed Village

[目的]通过与正常居住房、荒地、耕地作对比,研究废弃宅基地土壤肥力状况。[方法]应用Fuzzy综合评判法即运用模糊数学和相关分析的原理,对土壤肥力进行数值化的综合评价。[结果]耕地中土壤肥力质量主要集中在Ⅳ等级(占38.10%),Ⅰ等级占4.76%;荒地和居住房的土壤肥力质量没有Ⅰ、Ⅱ等级,荒地的土壤肥力质量Ⅲ等级最大(占32.00%),居住房的土壤肥力质量Ⅳ等级最大(占43.75%)。废弃宅基地的土壤肥力质量Ⅰ、Ⅱ、Ⅲ等级的百分比都高于耕地、荒地和居住房,3个等级的百分比和达到64.29%,分别是耕地、荒地和居住房3个等级的百分比和的1.69、2.01、3.43倍。[结论]该研究为空心村土地的农业生产提供理论依据。

[Objective] Compared with living house,wilderness and cultivated land,soil fertility quality of abandoned homestead was assessed. [Method] The method of fuzzy comprehensive assessment was used to evaluate soil fertility quality. [Result] The soil fertility quality of cultivated land mostly belonged to the forth grade. In the first grade,the soil fertility quality of cultivated land only accounted for 4.76%. The soil fertility quality of living house and wilderness didn＇t reach the first grade and the second grade. The soil fertility quality of wilderness land mostly belonged to the third grade accounting for 32%,and the soil fertility quality of living house mostly belonged to the fourth grade accounting for 43.75%. The ratio of first,second,third grade of soil fertility quality of abandoned homestead was respectively higher than those of living house,wilderness and cultivated land. The sum of the first,second and third grade of soil fertility quality of abandoned homestead was 64.29%,and was respectively 1.69,2.01 and 3.43 times the sum of cultivated land,wilderness and living house. [Conclusion] The study provided theoretical basis for the agricultural production in hollowed village.
