2.1 技术简介

技术定义:

Contour-felled log erosion barriers is a hillslope stabilization technique.

2.2 技术的详细说明

说明:

A foreseen wildfire is expected for the summer 2015 in the Caroig mountain range. Area was afforested by Aleppo pines during last XX century and nowadays landscape is composed by mature Aleppo pines at different stages of development and, the understory shrub vegetation.
The research team of the University of Valencia will implement an experiment based on the contour-felled log erosion barriers technique to capture and measure post-fire soil losses in a natural burned landscape

Purpose of the Technology: Contour-felled log erosion barriers are designed to increase detention and infiltration of overland flow, thereby reducing runoff and sediment transport capacity

Establishment / maintenance activities and inputs: The standard installation technique consists of felling burned trees and laying them on the ground along the slope contour. Each log is anchored in place and gaps between the log and the soil surface are filled with soil to create a storage basin on the upslope side of the log where overland flow is trapped

Natural / human environment: The Aleppo pine trees in the region are typically planted as monoculture for wood production. The landscape reflects a long history of intense land management, with a mosaic of (semi-)natural and man-made agricultural (terraces) and afforested lands. Since the 1970´s, however, wildfires have increased dramatically in frequency and extent, driven primarily by socio-economic changes.

3.1 该技术的主要目的

• 减少、预防、恢复土地退化

3.2 应用该技术的当前土地利用类型

注释:

Major land use problems (compiler’s opinion): When high fire severity, it is expected a runoff and soil erosion increase, resulting in a decrease of on-site fertility and derived off-site effects such as loss of water quality, reservoirs water volume storage, higher risk of flooding and human beings damage.

Major land use problems (land users’ perception): Loss of wood resources.

Plantation forestry: Post-fire assessment

Forest products and services: Other forest products / uses (honey, medical, etc.)
