| 摘 要： | 广东山地丘陵面积约占总面积的70％,山地丘陵在广东经济发展中占有重要地位。本文根据长达5年的南方山区土壤资源考察及前人的研究成果,论述了广东山地丘陵土壤中有机质、全氮、颗粒组成、代换性能、矿质营养元素和土壤水分等的特点。建议根据山地土壤资源的优势和生态系统的脆弱性,实行保护性开发、建立良性人工生态系统,因地制宜,因土种植,合理施肥和实行人工灌溉等土壤水分的调控措施。

| Abstract: | Mountain and hill make upabout 70% of the total area of Guangdong province, so they occupy an important position in developing economy of this region. Based on data from 5 years' investigation and on results from other researchers, this paper deals with the characteristics of organic matter, total nitrogen, particle composition, cation exchange capacity, mineral nutrient, and rnoisture status of soils in mountain and hill. Some suggestions for rational utilization of soil resources in the region are put forward as the following: implementing protective exploitation, establishing fine artificial ecosystems, planting crops suited to local conditions and soll types, applying fertilizer reasonably, and adopting artificial irrigation and other measures to adjust soil moisture regime. |
