The content of total nitrogen and total potassium and total phosphorus in seven study sites was ranged from 10 . 04g kg - 1 to 0 . 40 g kg - 1 . 60 . 63 g kg - 1 to 22 . 23 g kg " and 6 . 27 g kg - 1 to 0 . 66 g kg - 1 , respectively 在相同条件一f ，其分解过程中养分浓度的变化没有明显的规津性，可能的原因是，第一，王朗自然保护区内降雨量较少，年平均温度软低，凋落物分解较漫，暂时还没有显示出明显的规律性。
This study aims at censusing of the panda population , panda ' s exploitation of habitats and impacts of various human activities on the giant pandas and its habitats . the route transect method was used and plots were set along the route in each valley at wanglang 调查方法是在王朗保护区内设置样线，沿样线设置样方，在样方中收集大熊猫各类痕迹的数量、特征、空间位置和生物与非生物环境因子。
The study site , wanglang nature reserve , located in pingwu county , sichuan province , china . the reserve was established in 1963 as one of the first four reserves set up for giant panda protection and as such holds some of the best high altitude primary forest and flora to be seen in china from 40 varieties of rhododendrons to wild roses and meadow flowers 王朗国家级自然保护区位于四川西部平武县境内，是全国建立最早的四个以保护大熊猫等珍稀野生动物及其栖息地为目的的自然保护区之一，它地处全球生物多样性核心地区之一的喜玛拉雅? ?横断山区，保持了完整的自然生态系统。
In 1980s diet bamboo of the giant panda was blooming . all these are responsible for the decrease of the population size of the giant panda . to prevent the further degradation of the panda habitats and protect this endangered species , we should assess impacts of human duisturbance on the giant panda and its habitats 为确切掌握大熊猫的数量、分布、栖息地环境等情况，制定切实可行的保护管理计划，我们以王朗自然保护区的大熊猫调查资料对其栖息地情况进行了详细研究，王朗自然保护区是岷山的腹心地带，保护好这个大熊猫种群是保护大熊猫物种的重要组成部分。
Seven plots selected from wanglang reserve were distributed in different types of forest and at different altitude , and different plot has different microclimate . soil property , microbial population , soil nutrient content of forest soil were determined in wanglang natural reserve , from may to october 2002 to july 2003 , the ecological distribution of three main groups , bacteria , actinomycete and fungi were determined in the forest soils by the cell enumeration methods . six kinds of physiological groups , including ammoniation bacteria , nitrification bacteria , nitrosification bacteria , aerobic autogenesis azotobacter , aerobic cellulose - decomposing bacteria and anaerobic cellulose - decomposing bacteria were enumerated by the most - probable number ( mpn ) 2001年10月在王朗自然保护区内设立了3个定位研究样地和4个临时样地，通过多次现场采样与室内实验分析，测定了白桦林、岷江冷杉林、紫果云杉林、绣线菊-羊茅群落、羊茅群落及高山柳灌木丛等6种不同植物群落内土壤微生物三大类群数量、功能微生物数量、土壤养分，并在固定样地内使用埋袋法进行了三个埋藏深度的凋落物分解袋试验，初步研究了枝条、阔叶、针叶等凋落物组分在不同分解阶段所含养分的动态变化。
At first , the writer particularly introduces the theoretical frame of the development of ecotourism in sichuan wang lang nature reserve after summarizing simple content of nature reserve and ecotourism . following , the author has narrated the environmental condition such as geologic background and landform characteristics and has a eco - tourism proposition 论文首先对自然保护区与生态旅游进行了简单概述，然后叙述了王朗自然保护区的地质背景、地形地貌等生态旅游开发的环境条件，详细介绍了王朗自然保护区的生态旅游开发条件，并作了生态旅游发展构想。
