Abstract:

Studying the characteristics of land use change and exploring pathways for its rational utilization are of great significance for regional sustainable development. Taking the changes in farmland area of the Horqin Sandy Land as an entry point, this paper reviews the historical evolution and current status of farmland area in this region, focusing on the impacts of farmland area changes on regional groundwater and farmland wind erosion. Effective approaches and methods for controlling farmland dust sources are proposed. It is recommended that farmland management in the Horqin Sandy Land include: enhancing the monitor and early warning systems for farmland in dust source areas; strengthening the construction of farmland windbreak systems through comprehensive development and management of shelterbelts to fully leverage their critical windbreak functions; reducing wind erosion and enhancing soil conservation capacity by implementing conservation tillage and winter cover cropping; improving integrated management of soil moisture and nutrients by vigorously promoting water-saving irrigation techniques and soil organic fertilization measures to achieve efficient utilization of water-fertilizer resources and comprehensive enhancement of soil quality. Implement classified treatment and adjusted management for different rainfed and irrigated farmlands to enhance comprehensive governance efficiency.

Key words: Horqin Sandy Land, land use, farmland area, dust source, soil quality
