我国喀斯特石漠化地区林下经济种植模式及问题分析
Analysis of Patterns and Problems of Understory Planting in Karst Rocky Desertification Areas of China
【摘要】 由于我国喀斯特石漠化地区人地矛盾突出、林地与土地利用率低、森林生态系统破坏严重,改善喀斯特地区森林生态系统的经济功能、防控石漠化恶性演替仍是当下亟需解决的艰巨任务。林下种植是一种经典的立体复合林业生产经营方式,能够实现林地资源最大利用化、缓解人多地少的矛盾、推动区域经济循环可持续发展、保障林农经济效益稳步增长,最终达到林业经济、农业发展和生态建设同步优化的目标。文中主要分析了喀斯特石漠化地区8种代表性林下种植模式的特征、效益及不足,并提出各林下种植模式关于结构优化升级、调整改善方面的核心对策,以期为喀斯特地区石漠化治理与林业发展提供理论支持与借鉴,确保生态、经济、社会效益的同步优化。
【Abstract】 The fragile ecological environment of karst rocky desertification area in China, which causes the prominent contradiction between man and land, the low utilization ratio of forestland and other land, and the seriously damaged forest ecosystem, demands the improvement of the economic function of forest ecosystem and the control of the malignant succession of rocky desertification, which are difficult tasks urgently to be solved. Understory planting is a classical way of vertical and compound production and management of forests, which can maximize the utilization of forest land resources, alleviate the contradiction of more people and less land, promote the sustainable and circular development of regional economy, and ensure the steady increase of economic benefits of forest farmers, and can eventually achieve the objectives of synchronic optimization of forestry economy, agricultural development and ecological amelioration. This paper mainly analyzes the characteristics, benefits and defects of 8 typical understory planting patterns in karst rocky desertification areas, and comes up with the core countermeasures for structural optimization and upgrading, adjustment and improvement of the understory planting patterns. This study is to provide theoretical support and reference for rocky desertification control and forestry development in karst area for ensuring the simultaneous optimization of ecological, economic and social benefits.
