Effect Evaluation of Slope Protection for Herbs Based on the Principal Component Analysis
Slope protection with vegetation is a new technology which is using vegetation to preserve water and soil, so reduce slope instability and corrosion, simultaneously beautify ecological environment. Using vegetation for slope protection can protect slope, and can overcome the shortcoming of traditional slope protection ways.This article takes Northeast Forestry University tree farm as an experimental field. According to climatic conditions of northeast area, soil texture conditions of highway slopes and other conditions, this text selects 6 different common herbs to plant, observes ecology compatibility and preserving soil ability of each kind of plant, then uses mathematical method to appraise slope protection effect of each kind of plant.Results indicate that different type of grass has different slope protection effect.
