The Micang Mountain area is one of the top-priority construction areas of the Long-range Protection Engineering Projects. Starting from soil water and thermal behaviors, soil nutrient properties and functional materials of soil fertility, etc. this paper studies and evaluates soil fertility features of vertical zonification; and points out that the Yellow Brown soil distributed at a higher altitude keeps better fertility while the Yellow Loamy soil spread at a low altitude appears to have some poor...

The Micang Mountain area is one of the top-priority construction areas of the Long-range Protection Engineering Projects. Starting from soil water and thermal behaviors, soil nutrient properties and functional materials of soil fertility, etc. this paper studies and evaluates soil fertility features of vertical zonification; and points out that the Yellow Brown soil distributed at a higher altitude keeps better fertility while the Yellow Loamy soil spread at a low altitude appears to have some poor symbols in structures, soil body configuration, nutrient perporties and qualities of functional materials of soil fertility. This is regarded as the results of soil degradation. Also, this paper suggests some measures to be adopted including readjustment of tree species structures, fertilization in accordance with soil surveys, and establishment of protection area of soil rlsources in the Micang Mountain areas.

米仓山地区是“长防工程”建设重点区域之一。本文从土壤水热性状、营养特点和肥力功能物质组成等研究评价了其垂直地带性土壤的肥力特征。指出本区分布较高海拔的黄棕壤等保持了某些良好的肥力特征,而分布海拔较低的黄壤等则在结构、土体构型、营养性及肥力功能物质品质等出现某些不良征兆,认为是退化结果。提出了调整树种结构、测土施肥、建立米仓山土壤资源保护区等措施。

This paper deals with soil material leaching, fertility features,and element transport and enrichment characteristics of soils of some typical forest ecosystems in integrated control experimental plot at Niujiaotang, Wuhua County, Guangdong Province. The results showed that not only the fertility conditions but also the soil mechanical compositions, element transport and enrichment characteristics and some other genetic features were affected by the difference of ecosystems due to the factors of water loss and soil erosion, et al. There were some distinct and regular differences in soil ba values, Sa values, EI, LA and in fertility factors such as OM contents, total N, P, K and available N, P and K nutrients among forest land, semi-forest land and bare land.

本文研究了广东五华县牛角塘综合治理试验区几种典型森林生态系统土壤的物质迁移、肥力特性及元素迁移与富集传性,结果表明,生态类型的差异不仅会影响到土壤的肥力状况,同时由于水土流失等因素的影响,还会造成土壤机械组成、元素迁移富集特点以及其它发生学特性的差异,林地、半林地及光山地之间在这些方面也存在着明显的差异性.

The types, area, distribution and fertility feature of the soil resource in the main islands of Fujian Province were investigated. The total area of soil resource in the islands was 74013.5 hm 2, which was 72.[KG-4]97% of the total land area of the islands. The soil was classified as 5 soil orders and 6 soil types. Major soil types were lateritic red earth, coastal solonchak and eolian sand soil. The area of them was 75.90% of the total of island soil. The fertility feature of island soil was lower...

The types, area, distribution and fertility feature of the soil resource in the main islands of Fujian Province were investigated. The total area of soil resource in the islands was 74013.5 hm 2, which was 72.[KG-4]97% of the total land area of the islands. The soil was classified as 5 soil orders and 6 soil types. Major soil types were lateritic red earth, coastal solonchak and eolian sand soil. The area of them was 75.90% of the total of island soil. The fertility feature of island soil was lower content of organic matter, N deficiency, richer in P and K, slight acidity, sandier texture and lower CEC. The rational utilization of the soil resource in the main islands was discussed based on the analysis of situation and problems.

调查研究了福建省主要海岛土壤资源的类型、面积、分布及其肥力状况.全省主要岛屿土壤资源总面积为74013.5hm2,占调查岛屿土地总面积的72.97%,分属5个土纲6个土类,以赤红壤、滨海盐土和风沙土为主,占土壤资源总面积的75.90%.海岛土壤有机质含量偏低,普遍缺N,P、K水平较高,呈微酸性反应,质地偏轻,保肥供肥能力弱.在分析土壤资源利用现状和存在问题的基础上,进一步探讨了全省主要海岛土壤资源合理利用的对策
