基于GIS的山地耕地质量定级研究——以霍山县为例
|
摘要
耕地是农业发展和农民收益的基础,其质量的好坏会带来不同的社会、经济以及环境效益。本文基于GIS技术,通过因素法定级路线,以霍山县为例,对山地耕地质量定级过程及结果进行分析,研究结果表明,霍山县耕地质量总体一般,各等级耕地交错分布,主要是三级地和四级地分布较多,且各级地呈现出类正态分布趋势,整体耕地质量趋势呈现从东北高西南低,这和霍山县地势情况一致。海拔较低,地势平缓,交通比较便利,耕地质量较好,地势起伏较大,离主干道、水系较远的地区,耕地质量较差。耕地质量的好坏受到自然、社会、区域三者协同作用,自然因素及区域因素影响较大。
Cultivated land is the basis of agricultural development and farmers' income, and its quality will bring different social,economic and environmental benefits. Based on GIS technology,this paper analyzes the quality grading process and results of mountain arable land by taking Huoshan county as an example.The results show that the quality of cultivated land in Huoshan county is generally general, and the arable land of each grade is staggered, mainly at the third level. There are many distributions in the ground and the fourth level, and the various levels show a normal distribution trend. The overall cultivated land quality trend is from the northeast to the southwest, which is consistent with the situation of Huoshan county. The altitude is low, the terrain is gentle, the traffic is relatively convenient, the quality of cultivated land is good, the terrain is fluctuating, and the area of cultivated land is poor in areas far away from the main road and water system. The quality of cultivated land is synergistically affected by nature, society and region, and natural factors and regional factors have a greater impact.
