摘要/Abstract

摘要： 耕地是从事农作物种植的土地，为一个复杂的生态经济系统。影响耕地质量的主要因素通常有自然因素、社会经济因素和区位因素等，通过耕地质量影响因子的分析并建立衡量耕地质量变化的指标体系，对耕地逆转趋势的早期预警与耕地质量问题的及时发现，是非常必要的。从耕地质量状态、利用效率和耕地压力3个方面入手，运用SPSS软件对影响湖南省浏阳市耕地肥力的众多因素因子进行了取舍，并综合考虑地块区位、交通条件等状态因素，建立了耕地质量状态的评价指标体系，同时结合地块上作物的投入-产出效率和来自外界环境的耕地质量压力建立了基于地块尺度上的县级耕地质量评价体系，与此同时，对各指标因子的选取与量化进行了较系统的阐述，并以湖南省浏阳市作为研究对象进行了实证分析。

Abstract: The arable land, which takes an important role in cultivation, is a complicatedly ecosystem. The primary factors to affect the quality of the arable land are comprised of natural, socioeconomic and the geographic situation. Through the analysis of the factors to affect the quality of arable land and the establishment of indicator systems for measure the change of the quality of arable land, it is essential to preliminarily preclude the converted tide and to discover the problems of arable land in time. This paper is based on the theoretical framework of state-efficiency-pressure to assess the quality of arable land in land patch scale, used of the statistical software SPSS and analyzed the historical statistical data of Liu Yang city, Hunan Province, the different state-indicators to the fertile content of arable land quality have been established. The other indicators, such as the conditional factors of situation & transportation of land patch connected with the nearly town, the natural and economical utilization-efficiency of the corns in land patch, are designed to evaluate, and some particular indicators to evaluate a specific problem, such as land erosion-rate, qualitative degradations of arable land, rough cultivation, the transformation of arable land at random, are put forwards. With the framework and methods as previously mentioned, the 1 156 arable land patches of Liu Yang, Hunan Province are researched and analyzed.

Key words: quality of arable land, the assessing indicators system of arable land, state-efficiency-pressure model, Liu Yang City, Hunan Province
