Edge is an important landscape feature of fragmented tropical forest landscapes in Xishuangbanna, Southwest China. Little is known about the edge effect of plant temperature that plays a key role in growth and development of plants. The primary objective of this study is to characterize the changes in plant leaf temperature from a forest interior to the outside.

Edge is an important landscape feature of fragmented tropical forest landscapes in Xishuangbanna, Southwest China. Little is known about the edge effect of plant temperature that plays a key role in growth and development of plants. The primary objective of this study is to characterize the changes in plant leaf temperature from a forest interior to the outside. Leaf temperatures and other microclimatic elements were measured along a transect extending from the interior to the open field at south facing edge of a 3 hm 2 tropical dry seasonal rainforest fragment in Xishuangbanna. The findings showed that the influence range of edge effect of the leaf temperature ( T l) was 20 m into the forest and 16 m into the open field from the edge. The greatest horizontal change in the leaf temperature occurred near the edge ranging from -8 m to 12 m into the interior. From the interior to the open, the leaf temperature was found, comparing with air temperature ( T a), to show three categories of air temperature pattern ( T a> T l), middle pattern( T a= T l) and radiation pattern ( T a< T l). The relations of T l to T a were created at the interior, the edge and the open. The ecological impacts of the edge effect of the leaf temperature were also discussed.

Hainan Island is the biggest tropical island in China. It is a global ecological critical region and biological hotspot for its particular location, excellent climate, complicated habitat and ecosystem vulnerability. Tropical forest landscape was the only matrix in Hainan Island before. Recently, it has changed into a mosaic of several matrixes, patches, and corridors resulted from interrelated and different land types, vegetation types, land use modes and others.

Hainan Island is the biggest tropical island in China. It is a global ecological critical region and biological hotspot for its particular location, excellent climate, complicated habitat and ecosystem vulnerability. Tropical forest landscape was the only matrix in Hainan Island before. Recently, it has changed into a mosaic of several matrixes, patches, and corridors resulted from interrelated and different land types, vegetation types, land use modes and others. This evolve was obviously a process of human activities. However, tropical forest, still, is an important type of landscape diversity in Hainan Island. Researches on landscape diversity in Hainan Island were scare, and there was no uniform classification system on the development of landscape classification. A new classification system was proposed based on landscape ecological theory and the difference of climate, topography, soil, vegetation and land use mode. Five basic units (zone, tract, province, region and type) and two assistant units (sub and group) were used in this system. The tropical forest landscape in Hainan Island was regarded as a landscape province, belonging to global tropical forest landscape zone, Asiatic (oriental) tropical forest landscape tract and Chinese tropical forest landscape subtract. Based on the grade system of region, sub-region, type-group and type, this landscape province (Hainan Island) are divided as 6 landscape regions (east moist forest landscape, west semi-arid forest landscape, central-south mountainous forest landscape, tropical evergreen needle-leaved forest landscape, tropical bamboo landscape and tropical plantation landscape), 11 tropical forest landscape sub-regions represented by lowland valley tropical rain forest landscape, 26 tropical forest landscape type-groups represented by tropical lowland valley Dipterocarpaceae forest landscape and lots of types or subtypes represented by dominant genus and species. Landscape province was named after zonal climate and vegetation type or land use mode; landscape region was named after topography and vegetation type; landscape type-group was named after habitat and vegetation group; type was named after habitat and dominant species or community group. Landscape province was based on zonal climate and vegetation type or land use mode; landscape region was based on topography and vegetation type; landscape type-group was based on habitat and vegetation group; type was based on habitat and dominant species or community group. Generally, this classification system represents the landscape diversity of tropical forest in Hainan Island though it was a primer study. Further studies are needed in order to better understand the landscape diversity of Hainan Island.

依据景观生态学原理,按地貌、气候、土壤、植被和土地利用方式的分异,以带、域、省、区、类型为5个基本单位及亚、组等为辅助单位,组建海南岛热带森林景观类型分类体系。把海南岛热带森林景观作为省级单位,它隶属于全球热带林景观带、亚洲(东方)热带林景观域、中国热带林景观亚域,其下划分为东部潮湿森林景观、西部半干旱森林景观、中南部山地森林景观、热带常绿针叶林景观、热带竹林景观和热带人工林景观6个森林景观区;以热带低地沟谷热带雨林为代表的11个森林景观亚区;以热带低地沟谷龙脑香森林景观为代表的26个森林景观类型组;以热带低地沟谷青皮林为代表的54个森林景观类型。海南岛热带森林景观类型分类体系较全面地表达了海南岛热带森林景观类型多样性。
