河池地区石漠化治理现状及对策

Treatment Status and Countermeasure of Rocky Desertification in Hechi

在充分了解河池地区石漠化治理示范区治理成效的基础上,总结出河池市石漠化成因,提出河池市石漠化治理区存在的生态问题并对其原因进行剖析,得到以下启示:我国西南地区的石漠化治理应该分区进行,极重度以及重度地区采用封山育林和生态移民等防治措施,轻度和中度地区则采用人工造林和退耕还林等措施,以恢复生态农业型植被为主,进行蓝莓、毛葡萄等新兴产业的开发,同时提高植被覆盖率,以达到资源合理利用与配置。最后建议将AFM丛枝菌根应用到石漠化治理中,可以改善土壤的理化性质,促进植物对矿质元素的吸收,提高植物抗旱性、抗病性及抗逆性,稳定生态系统,进而保障植物在受损与退化的生态系统中依然可以健康生长。

The causes and treatment status of rocky desertification were summarized based on full understanding treatment effect of rocky desertification treatment demonstration area in Hechi city. We put forward ecological problems and analysis its reasons in rocky desertification treatment region of Hechi city. We gained the important inspiration： the rocky desertification in southwest China should be district control. The prevention measures as closed forest and ecological migration are applied in extremely severe area and severe area, artificial afforestation and conversion of cropland to forest are applied in slight and mild area, in which mainly as restoration ecology agricultural vegetation, explore newly industry such as planting Vaccinium Spp and Vitis heyneana Roem. et Schult. Like this,on the one hand it can increase vegetation coverage; on the other hand it can make natural resources rational utilization and allocation. At last, we suggest that put the Arbuscular Mycorrhizal Fungi used in rocky desertification. It can improve soil physicochemical properties, promote minerals absorption of plant, increase drought-disease resistance and stress resistance and stabilize ecosystem, meanwhile guarantee plant health growth in damaged and degenerate ecosystem.
