Abstract
The remediation of inefficient garden land and defective forest land is one of the important sources and types of supplementary cultivated land in the comprehensive land remediation of the whole region. The remediation and development of inefficient garden land and defective forest land will effectively alleviate the multiple pressures faced by cultivated land at present. Taking Zhemu Town, Guilin City, China as an example, on that basis of the data of the third national land survey, using analytic hierarchy process, this paper selects six evaluation factors, including water source, traffic, slope, field concentration, farmland infrastructure and villagers’ will, to study the remediation potential of inefficient garden land and defective forest land in Zhemu Town, and delimits four potential divisions, in order to provide the basis for the arrangement of land remediation projects in Zhemu Town. The results show that the northern, central and western regions of Zhemu Town have great remediation potential.

Taking Zhemu Town, Guilin City, China as an example, on that basis of the data of the third national land survey, using analytic hierarchy process, this paper selects six evaluation factors, including water source, traffic, slope, field concentration, farmland infrastructure and villagers’ will, to study the remediation potential of inefficient garden land and defective forest land in Zhemu Town, and delimits four potential divisions, in order to provide the basis for the arrangement of land remediation projects in Zhemu Town
Using ArcGis10.3 analysis and calculation, the total area of remediation area of low-efficiency garden in Zhemu Town is 785.62 hectares, of which the first-class potential area covers an area of 394.19 hectares, accounting for 50.17% of the total area of remediation area of low-efficiency garden; The secondary potential area covers an area of 305.65 hectares, accounting for 38.91%; the third-level potential area covers an area of 61.84 hectares, accounting for 7.87%; the fourth-level potential area covers an area of 23.94 hectares, accounting for 3.05%
Scholars pay more attention to and study the potential of land remediation, but they mainly focus on the potential of agricultural land remediation, which provides a good research method for guiding the development of land remediation potential
Summary
The remediation of inefficient garden land and defective forest land is one of the important remediation types in the comprehensive land remediation of the whole region, the research on the remediation potential of inefficient garden land and defective forest land can effectively broaden the ways of supplementing cultivated land, provide strong support for solving the problem of balance between occupation and compensation of cultivated land (Liu, 2020), and have extremely important significance for promoting the scientific development of land resources in China and improving the use value of land resources. Analytic hierarchy process is used to analyze the remediation potential of inefficient garden land and defective forest land in Zhemu Town, the technical methods and the remediation potential were studied, it is suggested that the local people’s government can make reasonable arrangements for the land remediation project in Zhemu Town with reference to the analysis results and the wishes of the villagers, so as to contribute to improving the income of the villagers in Zhemu Town, promoting the coordinated development of economy, society and ecology in the project area, and realizing the rural revitalization strategy in China
