摘要/Abstract

摘要： 选择具有典型代表的辽宁北部平原区、河北坝上农牧交错区和渭北旱塬区农田防护林为研究对象,以主栽树种杨树林带为研究材料,针对每个特定类型区的主要自然灾害因子和防护目的,统计分析调查研究数据,确定了辽宁北部、河北坝上和渭北旱塬3类型区农田防护林可持续集约经营模型的最优经营参数.其中林带最适疏透度分别为0.25～0.35、0.20～0.30和0.275～0.375;主林带间距分别为450～500m、200m和200～250m;副林带间距分别为500～1000m、500m和350～50m;林带带面宽度分别为8m、9m和4.5～8m;林带行数分别为3～4、6和2～4;林带树木株行距分别为2m×1.5～3m、1.5m×1.5m和1.5～3m×1.5～3m,主栽树种的防护成熟龄分别为15～16a、14～15a和12～14a;防护成熟期分别为10a、10～11a和12～14a;最佳更新方式分别为隔带更新、半带嫁接更新和隔带更新.

Abstract: In this paper, with Populus in windbreaks/shelterbelts as study plants in three regions such as plain region of northern part of Liaoning, ecoton region of Bashang, Hebei Province, and semiarid tableland region of Weibei, Shanxi Province, and based on the main natural disaster factors and protection objective in these three regions, the data investigated in the study area were analyzed through statistics methods. The optimization management parameters were put forward for the sustainable and intensive management model of windbreaks/shelterbelts in three regions. The optimization porosity of shelterbelts/windbreaks in northern part of Liaoning, Bashang and Weibei should be 0.25～0.35,0.20～0.30, and 0.275～0.375 respectively. The distance between main belts should be 450～500m, 200m, and 200～250m respectively, and the distance between lateral belts should be 500～1000m, 500m, and 350～450m. The belt width should be 8m, 9m, and 4.5～8m respectively, with 3～4, 6, and 2～4 rows respectively. The spacing of trees should be 2m×1.5～3m, 1.5m×1.5m, and 1.5～3m×1.5～3m respectively. The protection mature age should be 15～16yr, 14～15yr and 12～14yr respectively. The protection mature time should be 10yr. 10～11yr. and 12～14yr respectively. The regeneration mode should be alternate strip-felling model, half strip-felling and engrafting model, and alternate strip-felling model respectively.
