摘要
喜马拉雅地区支持多样化的森林生态系统,土壤-植被相互作用在森林生产力和生物多样性保护方面发挥着重要作用。已经对森林生态系统的相互作用进行了大量的研究,然而,对影响社区管理的Van Panchayat森林的城市住区的邻近性知之甚少。本研究采用随机样方法进行植被分析,并随机采集样地土壤,每个样地有3个不同的深度(0-30、30-60和60-90 cm)。本文以Pauri镇附近的保留森林(RF)为基准,比较了Van Panchayat (VP)地区离市区近和远的森林土壤的理化性质和森林结构。结果表明,近城市VP林土壤有机碳(SOC)、水分含量和养分有效性均低于远城市VP林,且在RF立地最高。与VP森林相比,RF具有最大含水量(12.83%),持水量(82.1 %),体积密度(1.24 g cm⁻³),pH值(6.73),总碳(1.20%),总氮(223.95 kg ha⁻¹),有效钾(164.39 kg ha⁻¹)和有效磷(25.53 kg ha⁻¹)。研究结果表明,喜马拉雅山区城市周边社区森林对放牧、野餐地点和垃圾倾倒等人为影响的敏感性,突出了重点管理技术对喜马拉雅地区土壤健康和森林生态系统服务的重要性。
Physico-chemical variations in soils across urban proximity in van panchayat and reserved forests of the Western Himalaya
The Himalayan region supports diverse forest ecosystems, where soil–vegetation interactions play important role in forest productivity and biodiversity conservation.
The numerous studies have been examined for the interactions forests ecosystems, however, the little is known about the proximity of urban settlements that influences community-managed Van Panchayat forests. In the present study, vegetation analysis was conducted using random quadrats method and soil samples also collected randomly from the sites and each site has three different depths (i.e., 0–30, 30–60 and 60–90 cm). We compared the physico-chemical properties of soils and forest structure in Van Panchayat (VP) area forests located near and far from the urban areas, using a Reserved Forest (RF) near Pauri town as a benchmark. Results showed that soil organic carbon (SOC), moisture content, and nutrient availability were consistently lower in urban-proximate VP forests compared to remote VP forests and the highest value recorded in RF site. The RF exhibited the maximum moisture content (12.83 %), water-holding capacity (82.1 %), bulk density (1.24 g cm⁻³), pH (6.73), total carbon (1.20 %), total nitrogen (223.95 kg ha⁻¹), available potassium (164.39 kg ha⁻¹), and available phosphorus (25.53 kg ha⁻¹) compared to VP forests. The findings illustrate that the susceptibility of peri‑urban community forests in the Himalayan hills to anthropogenic influences such as grazing, picnic spots and garbage dumping, underlining the importance of focused management techniques for soil health and forest ecosystem services in the Himalayan region.
