行走江河看中国｜松辽流域绘就粮安与生态共荣新图景

Core Viewpoint - The article highlights the transformation of the Songliao River Basin, emphasizing the integration of water management, land restoration, and ecological value realization to enhance food security and environmental sustainability in Northeast China [1][11]. Water Network Development - The Songliao River Basin has established over 600 irrigation areas exceeding 10,000 acres, covering 32% of the cultivated land with a total irrigation area of 1.8 million acres [4]. - Modern irrigation techniques such as "water-saving irrigation" and "drip irrigation" have been implemented, significantly reducing water usage while maintaining crop yields [5]. - The shift from traditional irrigation methods to precise water management has improved agricultural productivity and sustainability in the region [5]. Land Restoration Efforts - A multi-year "gully treatment campaign" has been initiated to restore eroded land, with significant investments leading to the treatment of 4,683 square kilometers of soil erosion and the protection of 1.374 million acres of farmland [7][8]. - The campaign has resulted in an annual increase of 330 million pounds of grain production, showcasing the effectiveness of land restoration efforts [7]. - Specific examples of successful land restoration include the transformation of eroded gullies into arable land in various counties, contributing to food security [8]. Ecological Value Realization - The region is exploring innovative practices for converting ecological value into tangible economic benefits, such as trading newly created farmland indicators from gully restoration projects [11][12]. - The first successful transaction of farmland indicators in the black soil area was completed, generating revenue that supports ongoing soil conservation efforts [12]. - The reduction of soil erosion area by nearly 10,000 square kilometers since 2020 indicates significant progress in ecological restoration and sustainable land management [12].
