Study on Agricultural Land Planning Based on Sustainable Planting Strategies

With the increasing global demand for food and the environmental pressures of climate change, sustainable agricultural land planning has become a critical area of modern agricultural research. This study, based on sustainable planting strategies, constructs a multi-objective integer programming model aimed at optimizing planting schemes for various types of farmlands to maximize agricultural economic benefits and enhance land use efficiency while considering ecological sustainability. The model incorporates multiple constraints, including land area limitations, crop rotation requirements, the necessity of planting legumes, and greenhouse planting area restrictions. The results demonstrate that through rational crop allocation and planting pattern planning, limited land resources can be effectively utilized, leading to significant improvements in crop yield and economic returns. Additionally, the long-term ecological impacts of different planting strategies are evaluated, confirming the model's practical value in agricultural decision-making. This research provides a scientific decision-support tool for agricultural managers and policymakers, contributing to the sustainable development of agricultural production.
