Undergraduate

• Biotechnology

Bored by the endless experiments in the lab

• Ecology

Because of many travels, got the new interest in Ecology.

My trips

Why Yunnan?

• Richest biodiversity.

• Minority culture.

--- 26 out of 56 nations

• Common boundary with several countries.

• Wonderful landscape : snow mountain, stone forest, primary forest and so on

Master Program: International tropical and

subtropical forest

My foreign classmates are neally all from tropical and subtropical country :

Vietnam, Indonesia, Phillipine, Nepal, China, Peru, Brazil, Sudan, Ethiopia, Cameroon

Others are from Japan, Belgium, USA, Germany

Why Germany?

• One of the most developed country all over the world

• Long history and colorful culture• The origin of -- The word of sustainability -- Near to nature forest• Great efforts to protect the environment• Strong-minded and hardworking people • Free tuition

Courses• Sixteen lectures

-- Biometric data analysis and forest dynamics -- Ecopedology of the tropics and subtropics -- Forest development policy -- Forest inventory -- Forest utilization and wood processing -- International forest economics -- Project planning, management and evaluation -- Tropical forest ecology and silviculture -- Applications of remote sensing and GIS -- Bioclimatology and global change -- Dryland forestry and methods in silviculture -- Forest genetics and plantation forestry -- Forest protection and agroforestry -- Forestry in Germany -- Impacts of forest disturbance

-- Multidisciplinary Research in Tropical

Production Systems

• Mini project

“ Managing sustainable forestry systems (in Germany)”

-- My topic : Bioenergy utilisation

• Main project

-- Soil respiration rate measurement in Sulawesi, Indonesia

Storma• Full name : Stability of Rainforest margins

in Indonesia

Storma – interdisciplinary Objectives-- find out the destabilisation of forest margins -- analyze those factors, processes and principles

which facilitate the maintenance of stability there Sub – project A Social and economic dynamicsSub – project B Water and nutrient turnoverSub – project C BiodiversitySub – project D Land use system

Storma :Cooperatory

Two universities from Germany

University of KasselUniversity of Goettingen

Two universities from Indonesia

Institut Pertanian Bogor (IPB) in Java The Universitas Tadulako (UNTAD) in Palu, Central Sulawesi

Sub-project B

B1 Effects of land use on the exchange of water, carbon dioxide and energy between the rain forest margin area and the atmosphere   

B2 The influence of pedo-hydrological changes on water and

nutrient cycles    B3 Nitrogen oxide emissions from old-growth tropical rainforests

and land use systems  B4 Changes in the hydrological cycle along a gradient of forest

use intensity       

Study Site

Palu, Sulawesi

Description of the site

• located on south of the equator on 119° eastern longitude

• controlled by the Australian-Asian monsoon system

• annual precipitation of about 2500 mm • a mountainous region with peaks up to 2600
