左江流域种植业区划

THE REGIONALIZATION OF CULTIVATION IN ZUOJANG RIVER BASIN

左江流域六县（市）地处桂西南喀斯特地区，区内农业资源和生产水平各有差异。为了配合该地区经济的全面开发，我们收集了该地区七十一个行政乡农业生产有关的特征数据，运用数学的方法──聚类分析法和电子计算机技术，对该地区农业的空间布局进行合理调整──种植业类型区划分，并分别论述各类型区的特点及今后发展方向。为该地区今后在农业生产上做到宜地适种、扬长避短，并在此基础上向区域化、集约化的农业迈进提供科学依据。

The six counties and city of the Drainage Area of Zuo River in Nanning District lie in the Karst area in southwest of Guangxi Province. There is disparity in agricultural resources and productive level within the area. In order to play along with the overall economic development of the area, we collected the digital data relative to the agricultural production of the seventy─one administrative villages in the area, using mathematical methods─cluster analysis and electrical computertechnology, to reasonably adjust the spatial allocation of agriculture in the area─the crop type regionalization, and discussed the features and developing trends of each type, providing a scientific base for the area to take effective measures according to its local conditions and give play to its strong points and avoid its shortcomings in agricultural production, and based on which, to stride forward in regional and intensive agriculture.
