- 摘要:
- 为提高东北次生林森林公园景观质量，在吉林市大石门沟森林公园次生林选择典型样地，采取了修枝、去除枯落物、清灌等技术措施对次生林林内进行处理。采用心理物理学派的美景度评价法（SBE）、相关分析和回归分析等方法，确定了次生林样地内景观质量指标和预测模型。结果表明：3种技术措施均能有效提高林内景观质量，清灌措施使林内景观美景度均值从29.8提升到70.3；修枝措施使林内景观美景度均值从38.3提升到58.3；去除枯落物措施使林内景观美景度均值从36.9提升到53.4。对照组美景度的模型如下：MSBE=-49.7+31.2X10 ，空间感（X１０）为主导因子（P<0.01）；清灌组的美景度回归模型：MSBE=-132+56.5X4，自然程度（X4）为主导因子(P<0.05)；修枝组的美景度回归模型：MSBE=-102.5+58.1X5，树木排列（X5）为主导因子(P<0.01)；去除枯落物组的美景度回归模型：MSBE=-73.2+39.6X1，树干形态（X1）为主导因子(P<0.05)。说明3种措施中提升景观质量效果排序，清灌＞修枝＞去除枯落物；采取不同的技术措施使原有次生林林内景观结构发生改变，影响景观美景度的主要因子也同时发生的改变。
- Abstract:
- For improving the quality of in-forest landscape in northeast secondary forest park，Jilin city Corn-growing Ditch Forest Park was taken as an example.Methods of pruning，cleaning shrub and litter-fall were chosen to clean the forest.The effects of quality of the in-forest landscape was determined by using SBE method,correlation and regression analysis.The results showed that the quality of in-forest landscape had remarkable improvement by using these technical measures.By cleaning shrub,the mean value of SBE of in-forest landscape had increased from 29.8 to 70.3;by pruning,the mean value of SBE of in-forest landscape increased from 38.3 to 58.3;by cleaning litter-fall,the mean value of SBE of in-forest landscape increased from 36.9 to 53.4.The dimensional feeling（X１０） was the main indicators that influenced on the control group landscape quality of secondary forest.The beauty degree model was built MSBE=-49.7+31.2X10 （P<0.01）;naturalness degree(X4） were the main indicators that influenced on cleaning shrub group landscape quality of secondary forest.The beauty degree model was built MSBE=-132+56.5X4.Trees arrangement(X5） was the main indicators that influenced on pruning group landscape quality of secondary forest.The beauty degree model was built MSBE=-102.5+58.1X5(P<0.01);trees form(X1） was the main indicators that influenced on cleaning litter-fall group landscape quality of secondary forest.The beauty degree model was built MSBE=-73.2+39.6X1(P<0.05).So，the descending order effect of the improvement quality landscape in these measures was cleaning shrub>pruning>cleaning litter-fall.At the same time，it had been taken some changes on the landscape structure and the main indicators that influenced on landscape quality by using three technical measures for improving the quality of forest landscape.
