Abstract

Community-based forest management practices var y according to biophysical and management factors . This study aimed to explain the vegetation conditions of community-based forest manage ment in Aik B ual and S e tiling village , Lombok Tengah . The study site was divided into protected forest area s (HL) in Aik B ual Village with a legal community forest permit (Aik B ual-HKm), HL in S e tiling Village with no legal community forest permit (S e tiling- N on Permit), and HL in Aik B ual Village with no legal community forest permit (Aik B ual- N on Permit). Field measurement was conducted in Ju ly 2018 by establishing 12 plots of 20 m x 20 m . Each plot consisted of subplots of 10 m x 10 m, 5 m x 5 m , and 2 m x 2 m to collect data of woody and non-woody plants with the criteria of diameter (D) as follows: D ≥ 20 cm, 10 cm ≤ D < 20 cm, 2 cm ≤ D <10 cm, and D < 2 cm with tree height of < 1,5 m, respectively . The results showed that Aik B ual-HKm, S e tiling- N on Permit and Aik B ual- N on Permit had 24, 13 and 22 species , respectively . Dominant species of vegetation at D ≥ 20 cm were Erythrina variegata and Swietenia macrophylla , at 10 cm ≤ D < 20 cm were Musa paradisiaca and Durio zibethinus , at 2 cm ≤ D < 10 cm was Coffea canephora, and at D < 2 cm were C. canephora and S. macrophylla . Vegetation diversity index (H' ) of plants at D ≥ 2 cm in Aik B ual-HKm was slightly higher (H'=1 , 78) than that in S e tiling- N on Permit (H ’ =1 , 04) and Aik B ual- N on Permit (H ’ =1 , 15) , although these are classified as moderate. The results illustrate d the possible differences of vegetation diversity in community-managed forest s with and without legal permission .

龙目岛Aik Bual村和Setiling村社区管理森林植被状况

基于社区的森林管理做法因生物物理和管理因素而异。本研究旨在解释龙目县Aik B al和S e tiling村社区森林管理的植被状况。研究地点分为具有合法社区森林许可证(Aik B al- hkm)的Aik B al村森林保护区(HL)、没有合法社区森林许可证的s e tiling村森林保护区(s e tiling- N on permit)和没有合法社区森林许可证(Aik B al- N on permit)的Aik B al村森林保护区(HL)。2018年7月，通过建立12个20 m × 20 m的地块进行了现场测量。每个样地由10 m × 10 m、5 m × 5 m和2 m × 2 m的子样地组成，收集木本和非木本植物的数据，其直径(D)标准分别为:D≥20 cm、10 cm≤D < 20 cm、2 cm≤D <10 cm和D < 2 cm，树高< 1.5 m。结果表明:Aik B al- hkm、S e tiling- N on Permit和Aik B al- N on Permit分别有24种、13种和22种。D≥20 cm的优势种为赤藓和大叶甜菊，10 cm≤D < 20 cm的优势种为天堂Musa paradisiaca和zibethinus, 2 cm≤D < 10 cm的优势种为canephora Coffea canephora, D < 2 cm的优势种为canephora和S. macrophylla。海拔≥2 cm的植物多样性指数(H′= 1.78)略高于S e tiling- N on Permit (H′= 1.04)和k B ual- N on Permit (H′= 1.15)，但均为中等。结果表明，在有法律许可和没有法律许可的社区管理森林中，植被多样性可能存在差异。关键词:农林业，土地权属，防护林，植被分析

期刊介绍： The Journal of Symbolic Logic publishes research in mathematical logic and its applications of the highest quality. Papers are expected to exhibit innovation and not merely be minor variations on established work. They should also be of interest to a broad audience. JSL has been, since its establishment in 1936, the leading journal in the world devoted to mathematical logic. Its prestige derives from its longevity and from the standard of submissions -- which, combined with the standards of reviewing, all contribute to the fact that it receives more citations than any other journal in logic.
