ANALYSIS OF USE POTENTIAL OF FARMLAND PRODUCTIVITY IN DIFFERENT TYPICAL AREAS OF GUANGDONG PROVINCE
摘要
Abstract
On the basis of the calculation of the three-layered farmland productivity in Guangdong Province, analysis was done of spatial patterns of theoretical use potentials ( prospective production potential) and achievable use potentials (near-future production potential) of the farmlands in the five typical areas of Guangdong Province, and based on the grading of the farmlands of the province and the analysis of differentials and correlations of the factors involved in grading of farmlands, it was also done of keys to promoting farmland productivity in these typical areas in near future. Results show that the farmlands in North Guangdong and Chaozhou-Shantou region are the highest in land-use intensity, leaving little production potential available for tapping and little room for productivity promotion in future. The Chaoshan Plain in particular has almost exhausted the productivity potential of some of its farmlands. In Leizhou Peninsula, Central-south Guangdong, and Southwest Guangdong, the farmlands still have some productivity potential, so their productivities may be raised by quite a large margin in future. In Leizhou Peninsula, improving its probability of irrigation is the key way to raising its farmland productivity, while in Central-south Guangdong, and Southwest Guangdong, improvement of their farmland infrastructure and probability of irrigation is the main orientation of their efforts to increase farmland productivity, and raising soil pH and building up soil fertility are other two. North Guangdong, however, will have to rely on better probability of irrigation, higher soil organic matter certification and leveled farmlands. The Chaoshan Plain does not have much potential to raise its farmland productivity, yet it still could by ameliorating its coastal salt-affected soil.关键词
