Abstract

The Nature Reserve of Panjalu Lake is one of the oldest conservation area in Indonesia. As a conservation area, Panjalu Lake has different species of flora that are useful as germplasm conservation, science and education. This study aims to know the potential of vegetation species diversity for ecotourism development at Nature Reserve of Panjalu Lake. The inventory method used is line plot sampling with intensity 15 % in two paths of 500 m (adjusted according length of the area) and 20 m width. Spacing between lines is 200 m and spacing between observation plot is 100 m. Within each path, 50 m x 20 m observation plots were established. The results showed that there are three species of seedlings with highest IVI, namely: Dysoxylum densiflorum Miq. (47.64 %), Calamus zollingerii (47.64 %), and Sterculia macrophylla Vent. (44.37 %). The four species at sapling stage with highest IVI are: Litsea cassiaefolia (114.29 %); Dysoxylum densiflorum Miq (57.14 %); Litsea sp. and Endiandra rubescens Miq (14.29 %). Three species at pole stage with highest IVI, namely: Dysoxylum densiflorum Miq. (143.04%); Litsea cassiaefolia (99.78 %) and Artocarpus elasticus Reinw 9.53 %). Three species at tree stage with highest IVI, namely: Dysoxylum densiflorum Miq (147.924 %), Litsea cassiaefolia (68.753 %), and Eugenia fastigiata Miq ( 31.410 %). Keywords: conservation area, Nature reserve of Panjalu Lake, vegetation structure, Important Value Index

潘贾鲁湖自然保护区植被物种多样性对生态旅游发展的潜力

潘贾鲁湖自然保护区是印度尼西亚最古老的保护区之一。作为一个保护区，潘贾鲁湖有不同种类的植物群，可用于种质资源保护、科学和教育。本研究旨在了解潘贾鲁湖自然保护区植被物种多样性对生态旅游发展的潜力。使用的清查方法是在500米（根据区域长度调整）和20米宽的两条路径中进行强度为15%的线图采样。线间距为200 m，观测点间距为100 m。在每条路径内，建立了50 m x 20 m的观测点。结果表明，有三种幼苗的IVI最高，即：密花脱氧菌Miq。（47.64%）、唑林葛（47.64%。（44.37%）。幼树期IVI最高的4种为：决明子（114.29%）；密花脱氧菌（57.14%）；Litsea sp.和冬凌草（Endiandra rubscens Miq）（14.29%）。三个IVI最高的极期物种，即：密花脱氧菌。（143.04%）；决明果（99.78%）和弹性Artocarpus elasticus Reinw（9.53%）。三个树期IVI最高的物种，即：密花脱氧菌（147.924%）、决明子（68.753%）和尖叶Eugenia fastigiata Miq（31.410%）。关键词：保护区，潘贾鲁湖自然保护区，植被结构，重要价值指标
