In terms of absorption proportion, element N was the nutritional limiting factors in spring, summer and autumn, while element P in winter. However, both became the nutritional limiting factors in all years in term of absolute absorption.

从浮游植物吸收N、P 的配比分析， N为春、夏、秋3 季的营养限制因子， P 为冬季的营养限制因子，但从N、P 的绝对值看， N 和P 都是全年的营养限制因子，因此其水质营养类型属于亚热带贫营养型。

Fossils are well preserved. 2. The results of comparative analysis of South China Karst Nominated Sites (Phase 1) with similar sites: among the stone forests all over the world, Shilin Stone Forest in Yunnan is neither the tallest nor the oldest one, but the most complicated in the evolution history and richest in the forms. It represented a unique evolvement mechanism of stone forest development; Libo cone karst, possesses not only the most typical karst cones, but also the most complex assemblages of the cone karst.

"中国南方喀斯特"第一批世界自然遗产提名地与相似地点进行对比分析结果：云南石林喀斯特不是最高的石林，也不是最古老的石林，但云南石林形成演化历史最复杂，石柱的形态最丰富，代表一种独特的石林形成演化机制；荔波锥状喀斯特不仅锥峰单体最典型，而且锥状喀斯特地貌组合形态最丰富，代表典型的锥状喀斯特地貌特征，反映出大陆热带–亚热带锥状喀斯特的地质演化模式与过程。

在亚热带浙江金衢盆地的丘陵双季水稻田的早、晚稻期间研究了白背飞虱的被寄生和被捕食作用下的存活率。早、晚稻白背飞虱卵被缨小蜂寄生率分别为 1 1 %和 1 6 %，被捕食及未知因子死亡率分别为 2 3%和 1 6 %。

The major factors which hinder the sustainable management of Chinese fir plantation include not only the vulnerable subtropical red soil ecosystem which Chinese fir grow in, but also the unitary community structure and the biological characteristic of this artificial forest community. Additionally, the traditional culture system of Chinese fir including controlled burning lead to the degradation of soil ferti-lity.

影响杉木人工林可持续经营的因素是多方面的，主要和杉木人工林所处亚热带红壤区生态系统的脆弱性和杉木人工林群落的单一性及杉木生物学特性等有关，而传统杉木林培育过程中采取一系列传统的营林措施则加剧了林地地力衰退。
