摘要

本研究利用ENVI和ArcGIS软件,利用1987年、2002年和2018年的Landsat图像,对江户州Sokponba和Ehor森林保护区的状况进行了评估。问卷调查也是为了从被调查者中获取信息。研究显示,在研究的31年期间,索本巴森林保护区从1987年的28913.63公顷减少到2018年的1578.15公顷,而种植园和农田从1987年的15357.96公顷增加到2018年的43494.21公顷。eor保护区也从1987年的11128.86公顷减少到2018年的3242.28公顷。同样,种植园和耕地从1987年的1424.97公顷增加到2018年的9323.28公顷。政府故意将区域分配给木材承包商用于伐木,将保护区转为油棕种植园和农田的政策被确定为造成森林保护区枯竭的主要驱动因素。考虑到森林砍伐所带来的碳序列、温室效应(全球变暖)、洪水等后果,该研究建议重新造林和黄崖农业系统,以实现可持续的环境。

A Geospatial Assessment of Deforestation of Sokponba and Ehor Forest Reserves in Edo State
The study assesses the state of Sokponba and Ehor forest reserves in Edo state, with Landsat images of 1987, 2002 and 2018 using ENVI and ArcGIS software. Questionnaire was also administered to elicit information from respondents. The study reveals that within the period of 31 years under study Sokponba forest reserve has reduced from 28,913.63 ha in 1987 to 1,578.15 ha in 2018 while plantation and farmland increased from 15,357.96 ha in 1987 to 43,494.21 in 2018. Ehor reserve also reduced from 11,128.86 ha in 1987 to 3,242.28 in 2018. In the same vein, plantation and farmland increased from 1,424.97 ha in 1,987 to 9,323.28 ha in 2018. The deliberate government policies of allocating compartment to timber contractors for logging, conversion of reserves to oil palm plantation and farmland were identified as the major drivers responsible for the depletion of the forest reserves. Considering the consequential effects arising from deforestation such as carbon sequence, greenhouse effect (global warming) and flooding the study recommends reforestation and taungya farming system for sustainable environment.
