广西石漠化地区土地整治分区分析

Analysis on Land Consolidation Zoning in Rocky Desertification Region in Guangxi

为进一步研究广西石漠化地区土地整治,对石漠化土地利用现状和石漠化地区土地整治类型进行了分析,结合石漠化地区地形地貌,对广西石漠化地区土地整治分区进行了深入研究。结果表明:(1)广西石漠化地区主要地类是林地、其他用地和耕地;(2)石漠化土地整治类型必须为生态型;(3)石漠化土地整治类型划分为轻度石漠化土地整治类型、中度石漠化土地整治类型、重度石漠化土地整治类型和潜在石漠化土地整治类型四类;(4)石漠化土地整治分区按照各整治类型,结合地形地貌可分别划分为峰丛洼地整治区、峰丛谷地和岩溶平原整治区及岩溶丘陵山地整治区,各整治区适用的整治模式不尽相同。对广西石漠化地区土地整治分区的深入分析研究,可为乡村振兴时代背景下的广西石漠化土地治理提供参考。

In order to further study the land consolidation in rocky desertification area of Guangxi, the present situation of land utilization in rocky desertification area and land consolidation types in rocky desertification area were analyzed. Combined with the topography of rocky desertification area, the paper makes an in-depth analysis and research on the land consolidation zoning of rocky desertification area in Guangxi. The results showed:(1) The main land use types are forest land, other land and cultivated land in Guangxi rocky desertification area;(2) All of the rocky desertification land regulation types must be ecotype;(3) The rocky desertification land management types are divided into four categories, namely light rocky desertification land management types, moderate rocky desertification land management types, severe rocky desertification land types and potential desertification land types;(4) According to the different management types, combined with landform types, the partition of land management types in rocky desertification region can be divided into the regulation area of peak cluster depression, the regulation area of peak cluster valley and karst plain, and the regulation area of karst hills and mountains. The different rocky desertification land management modes are applicable to different land consolidation zoning. The in-depth study of land improvement zoning in Guangxi rocky desertification land is of great significance to Guangxi rural revitalization.
