    摘要:

    [目的] 对历年来陕西省荒漠化防治综合效益进行分析和评价,为该省制定防治荒漠化政策和发展规划,保护、改良和合理利用资源、实现可持续发展提供科学参考。[方法] 基于陕西省2011—2022年荒漠化治理中人工造林种草等相关数据,根据相关标准规定和前人研究经验,选择相应的生态、经济和社会效益计算指标和计算方法,进行综合评价。[结论] 陕西省荒漠化土地治理累计推广人工造林面积达8.36×105 hm2,2011—2022年期间,荒漠化综合防治工作在阻挡粉尘,防风固沙,提高土壤保氮量、保磷量和保有机量,涵养水源,固碳释氧等方面发挥了重要作用;同时,在碳汇林、饲草、造林种草节支、种子、果品、林下经济、“林(草)光”互补、生态旅游和森林康养8个方面经济效益突出,累计带动就业人数达1.5万人,农民累计收入达8亿元。[结论] 陕西省荒漠化综合防治对改善自然环境效益显著,也增加了就业机会、吸纳剩余劳动力、缓解就业压力,促进了人与自然和谐共生发展。

    Abstract:

    [Objective] The comprehensive benefits of desertification prevention and control in Shaanxi Province over the years were monitored and evaluated, in order to provide a scientific reference for the formulation of relevant policies and development plans in Shaanxi Province, as well as the protection, improvement, and rational utilization of resources to achieve sustainable development. [Methods] Based on monitored data related to artificial afforestation and grass planting in desertification control in Shaanxi Province from 2011 to 2022, and in accordance with relevant standards and previous research experience, corresponding indicators and methods for calculating ecological, economic, and social benefits were selected for comprehensive evaluation. [Results] The cumulative area of artificial afforestation promoted in desertification land management in Shaanxi Province reached 8.36×105 hm2 hectares. During the period from 2011 to 2022, the comprehensive prevention and control of desertification played an important role in blocking dust, windbreak and sand fixation, improving soil nitrogen and phosphorus retention, increasing soil organic matter retention, conserving water sources, fixing carbon and releasing oxygen. At the same time, outstanding economic benefits were achieved in eight aspects: carbon sequestration forests, forage grass, cost saving from afforestation and grass planting, seeds, fruits, agroforestry, complementary “forest (grass)-solar” systems, ecotourism and forest-based wellness programs. The cumulative employment reached 15 000 people, and the cumulative income of farmers reached 800 million yuan. [Conclusion] The comprehensive prevention and control of desertification in Shaanxi Province has significant benefits in improving the natural environment, increasing employment opportunities, absorbing surplus labor, alleviating employment pressure, and promoting harmonious coexistence and development between humans and nature.
