水土流失得到有效治理

Core Viewpoint - Soil and water conservation is essential for river protection and ecological civilization, with significant progress made in controlling soil erosion and enhancing ecosystem quality in key areas of China since the 14th Five-Year Plan [1][2]. Group 1: Achievements in Soil and Water Conservation - Since the 14th Five-Year Plan, over 340,000 square kilometers of soil erosion control area have been added, resulting in a net reduction of approximately 116,000 square kilometers of soil erosion, with a national soil conservation rate exceeding 73% [1]. - Key regions such as the upper and middle reaches of major rivers, the Northeast black soil area, and the Three Gorges Reservoir area have seen effective management of soil erosion, with a targeted reduction in soil erosion intensity by 15% to 20% in project areas [1][2]. - Specific initiatives include the construction and renovation of nearly 7,000 sediment retention dams in the Loess Plateau and the comprehensive management of 4 million mu of sloped farmland to ensure food security [1][3]. Group 2: Regulatory and Technological Innovations - The Ministry of Water Resources has established a comprehensive regulatory system for soil and water conservation, transitioning from traditional methods to a new model utilizing remote sensing technology for oversight [2]. - The integration of modern information technologies such as big data and cloud computing into soil and water conservation efforts is aimed at enhancing management efficiency [2][4]. - A digital platform for sharing information on soil and stone resources has been launched in several provinces to address challenges in construction projects [2]. Group 3: Economic and Community Benefits - The establishment of a mechanism for realizing the value of ecological products from soil and water conservation aims to ensure sustainable environmental protection while benefiting local communities [3]. - Recent transactions in Guizhou Province have generated 12.635 million yuan from ecological product value, with profits distributed to support watershed management and community welfare [2][3]. - The cycle of "governance—land increase—transaction—re-governance" is creating a positive feedback loop that effectively balances soil erosion control with the creation of new arable land [4].
