Based on the systematic Observational data,this paper deals with the dynamic changes of soil temperature under evergreen forest, upland of hills and rice production region on the plain of the Pearl River Delta; and discusses the effects of atmosphere temperature on the changes of the soil. Results showed that the difference in three dimension of temperature under ever-green forest region was larger than that in hills and plain region.

Based on the systematic Observational data,this paper deals with the dynamic changes of soil temperature under evergreen forest, upland of hills and rice production region on the plain of the Pearl River Delta; and discusses the effects of atmosphere temperature on the changes of the soil. Results showed that the difference in three dimension of temperature under ever-green forest region was larger than that in hills and plain region. It was found that the atmosphere temperature of the valley part of the south subtropical forest region was higher than that under coniferous, mixed or broad-leave forest;the surface temperature of the valley part is lower than that under coniferous forest but higher than that under mixed or broad-leave forest; the temperature of 20cm depth of soil layer of valley part was lower than that under coniferous and broad-leave forests but higher than that under broad-leave one. In the hills region with the same atmosphere temperature,there was still a slight difference in temperature of surface and soil layer due to differences in cultivated plants; while on the plain region almost no difference in annual atmosphere temperature, surface temperature and temperature in 20cm depth of soil layer was found. It indicated that there was clear difference in the temperature of atmosphere, soil surface and soil layer and its dynamic changes under different geomorphologic regions. Based on the research results, it is suggested that a year can be divided into two seasons, namely hot season with averege temperature >22℃ and cold season with average temperature <22℃; effective measures should be taken to regulate the soil temperature in order to satisfy the needs of normal growth of plants.

根据定位系统观测资料,阐述了南亚热带山地常绿森林区、丘陵旱作区和平原水稻区多种土壤的温度变化与气温的关系。观测研究结果表明:低山常绿森林区温度的三维空间差异比丘陵区、平原区大,丘陵区又比平原区大;南亚热带林区的气温、地表温、30cm土温比中亚热带的高,比热带的低:南亚热带林区的谷地气温高于针叶林、混交林和阔叶林,谷地地表温低于针叶林而高于混交林和阔叶林,谷地20m土温低于针叶林、混交林而高于阔叶林;在气温一致的丘陵区栽植植物不同,其地表温、土温略有差异;在平原水稻土区,年气温、地表温、20cm土温差异不大,但30cm以下土温渐显差异;不同地貌单元的气温、地表温和土温的年际差异、年平均温度、各月及0~12~24时的温度动态变化各具特征。根据气温与植物生长的关系,拟把气温>22℃的4~10月称热季、气温<22℃的1~3月及11~12月称作凉季。可因地制宜,根据气温和土温的变化特征与土壤水分和作物生长的关系,采取措施调节温度,以利于作物生长。

Panzhihua city is located in the Jinshajiang river hot and dry valley. The classic artificial forestation technique, by which preci pitation is the only water sources for the soil moisture of the forestation fiel d, has been used for revegetation in the view area from the city urban since 196 0s. It is difficult to establish forest vegetation in most of the view area by u sing the classic technique because of the dry soil moisture conditions during th e seven months dry season (November-May), and savanna is still the main veget ation type in the area. A number of small gullies are developed on the hill slop es with a long length and have considerable runoff during the wet season in the view area. Ever-green forests can be established if the soil moisture condition s are improved during the dry season. The micro-water harvesting technique is r ecommended to harvest the wet seasons runoff from the gullies on hill slopes f or improving the soil moisture conditions in the forestation fields during the d ry season.

攀枝花市地处金沙江干热河谷 ,视野区荒山植被建设 ,多年来一直采用雨养造林的技术路线 ,未能改变“雨季郁郁葱葱 ,旱季一片枯黄”的稀树草原植被景观。干热河谷森林植被难以恢复的主要原因是旱季干旱缺水。微水造林是采用微型水利工程措施 ,拦蓄雨季径流 ,改善坡地旱季土壤水分状况 ,造林育林。视野区山地山高坡长 ,毛支沟发育 ,雨季洪水径流充沛 ,非常适合采用微水造林的技术路线 ,营造四季常青的南亚热带常绿森林植被。

Based on 6 sampling plots of 10 m by 10 m,the limestone forest in Cuiyun,Simao of southern Yunnan was studied. The following results were given:(1)The limestone forest is dominated by the evergreen tree species Dracaena cochinchinensis. (2)In the total 600 m~2 sampling area,123 vascular species of 110 genera of 65 families were recorded. (3)In life form spectrum,phanerophytes contributes to 76.4% of total species,of which mesophanerophytes makes up 35.77%,liana phanerophytes 21.14%. In leaf size spectrum,the...

The following results were given:(1)The limestone forest is dominated by the evergreen tree species Dracaena cochinchinensis. (2)In the total 600 m~2 sampling area,123 vascular species of 110 genera of 65 families were recorded. (3)In life form spectrum,phanerophytes contributes to 76.4% of total species,of which mesophanerophytes makes up 35.77%,liana phanerophytes 21.14%. In leaf size spectrum,the forest is dominated by evergreen tree species with simple,mesophyllous leaves. (4)The forest,dominated by the evergreen tree species D.cochinchinensis,is not equivalent to classic monsoon forest in physiognomy,in spite of the fact that it is affected by seasonal dryness and contains a variable percentage of deciduous trees. It is considered to be a particular vegetation type on limestone in Southern Yunnan.

根据6个10m×10m样地的调查资料,对思茅翠云石灰岩山森林的群落学特征进行了分析研究,结果显示:(1)云南思茅翠云石灰岩山森林主要由常绿的剑叶龙血树形成单优群落,而群落内随乔木径级的增大,个体/种的数量逐渐减小。(2)该群落在600m2样地内,共计维管束植物123种,隶属于65科110属;其中乔木种类最为丰富,共有51种,隶属29科46属,而林下草本和层间藤本植物种类次之,灌木和附生植物种类较少。(3)群落主要以高位芽植物为主,其中又以中高位芽植物比例最大,占所统计总数的35.77%;在叶片生态学特征方面,群落以常绿(65.04%)、中叶(56.1%)和小叶(40.7%)、单叶(73.98%)、纸质(59.35%)、全缘(64.23%)、非尾尖(91.06%)为主。(4)该群落是一种基本上常绿或半常绿的森林群落,与经典的“季雨林”特征不符,应是一种滇南石灰岩山地上发育的特殊森林植被类型。
