Reserach on Characteristics Identification and Optimization of "Non-grain" Cultivated Land——Take Youjiang District ,Baise City,Guangxi Province as an Example
Accurately identifying the spatial characteristics of "non-grain" cultivated land and proposing control measures have positive signif-icance for accurate control of "non-grain" cultivated land. Taking Youjiang District as the research area,this paper identified the spatial char-acteristics of "non-grain" cultivated land in Youjiang District from the aspects of land type composition,slope distribution,landscape pattern,spatial adjacency,farming distance and transportation convenience.This paper proposed optimization and control measures for different types of "non-grain" cultivated land to in order to guide cultivated land to grow food. The results show that: The total amount of "non-grain" cultivated land in Youjiang District has reached 308.38 km2,mainly dry land,followed by garden land and forest land. The slope of "non-grain" culti-vated land is mainly greater than 6°,and when the terrain slope is less than 25°,the area of "non-grain" cultivated land increases with the in-crease of slope grade. "Non-grain" cultivated land is fragmented,with high spatial proximity to gardens and woodlands,and strong interac-tion. The closer to rural settlements (less than 800 m) and roads (less than 1200 m),the larger the proportion of "non-grain"cultivated land,and the spatial distribution of "non-grain"cultivated land is affected by cultivation distance and transportation convenience.
