Abstract

This study aims to quantify the spatial changes in farmland and model the efficiency of their use in mountainous territories, considering climate, topographical characteristics, and the development of exogenous geological processes. The main factors affecting land-use efficiency were assessed using qualitative and quantitative fact-finding, correlation analysis, and Geographic Information Systems tools. Accordingly, 14 major influencing factors were identified. A correlation and regression analysis was performed to resolve the modelling task. Using the correlation analysis methodology, the impact of each factor on the required indicator was quantified. The model developed shows that the land structure and production volume mainly influence land-use efficiency in agriculture. This finding fits well with pan-European studies. There is an annual trend towards more efficient use of farmland. In general, mountainous regions may provide high indicators of agricultural production under conditions of warm climate, sufficient moisture content, soil fertility and/or moderate fertilization, control of erosion processes, and predominance of low hypsometric heights. The developed model allows for optimizing the utilization of land resources, improving soil fertility and crop yields, and finding the right decisions for preventing the development of unfavourable processes.

山区农业土地的利用效率：数学建模

本研究旨在量化耕地的空间变化，并建立山区耕地利用效率模型，同时考虑气候、地形特征和外源地质过程的发展。利用定性和定量实况调查、相关性分析和地理信息系统工具，对影响土地利用效率的主要因素进行了评估。因此，确定了 14 个主要影响因素。为完成建模任务，进行了相关性和回归分析。利用相关性分析方法，量化了每个因素对所需指标的影响。建立的模型显示，土地结构和产量主要影响农业的土地利用效率。这一结论与泛欧洲的研究结果非常吻合。每年都有提高农田利用效率的趋势。一般来说，山区在气候温暖、含水量充足、土壤肥沃和/或施肥适度、水土流失过程得到控制、湿度高度较低等条件下，农业生产指标较高。所开发的模型可以优化土地资源的利用，提高土壤肥力和作物产量，并找到防止不利过程发展的正确决策。

期刊介绍： One of the most important challenges facing the contemporary scientific world are problems connected with environmental protection. Intensive development of industry and agriculture has led to a rise in living standards on one hand, but an increase in environmental degradation on the other. This degradation poses a direct threat to human health and life. Solving these ever-increasing problems which seriously endanger our civilization require the united efforts of scientists and field researchers of many branches. The "Polish Journal of Environmental Studies" publishes original papers and critical reviews on the following subjects: -Basic and applied environmental pollution research, including environmental engineering -Pollution control of atmospheric, water (marine and fresh), soil and biological materials -Determination of harmful substances, including their metabolic breakdown patterns -Analytical methods for metabolic breakdown patterns or other chemical degradation patterns in the environment and in biological samples -Development of new analytical methods, instruments and techniques for controlling pollutants -Circulation of pollutants in the environment and their effect on living organisms -Environmentally oriented catalysis -Hazards to human health and safety -Waste utilization and management -Land reclamation -Conference reports, scientific and technical reports and book reviews
