我国盐碱地综合利用的生态保护战略
Research on Ecological Protection Strategy for Comprehensive Utilization of Saline-Alkali Soil in China
摘要
Abstract
This study provided a systematic review of the ecological issues arising from the development of saline-alkali land in China.These included secondary salinization,the formation of groundwater depression cones,wetland shrinkage and functional degradation,and reduction in natural vegetation,as well as high remediation costs and pollution risks.In addition,it clarified the technological development pathways for the comprehensive utilization of saline-alkali land.These pathways encompassed four major directions:targeted strategies under a systematic management approach,cost-effective remediation under new ecological requirements,dual-force development through land-crop synergy,and specialized agriculture aligned with the broader concept of food.Furthermore,the study proposed an integrated strategy to strengthen the comprehensive management of saline-alkali lands,including emphasizing zonal rehabilitation of saline-alkali farmland,establishing a collaborative innovation system,and advancing fundamental theories and key technologies for sustainable utilization.It also recommended developing a tiered land-use model to support pilot programs for reserve resources and cultivated land,promoting specialized agriculture,enhancing productive capacity,advancing water-adapted planting,fostering innovation in water-saving agricultural technology,and strengthening ecological monitoring and impact assessment.This study provided the theoretical foundation and strategic support for ecological protection in the comprehensive utilization of saline-alkali land in China.关键词
