色彩是林内最强烈的视觉语言,秋季林内色彩差异尤为明显,研究色彩斑块布局对人工景观林质量提升有重要意义。为了探究色彩对生态景观林秋季景观质量的影响特征,以塞罕坝机械林场白桦纯林、2个密度的落叶松纯林、白桦-落叶松混交林为研究对象,选取了36张景观照片,采用ArcGis 10.3软件对照片进行矢量化处理,采用FRAGSTATS 4.2软件提取矢量化后照片的格局指数,采用美景度评价法(SBE)对照片中景观进行质量评价,美景度计算用的是标准化处理后的数据,故对照照片为随机1张照片。通过比较秋季4个林分色彩斑块形状指数(LSI)、香农多样性指数(SHDI)、香农均匀度指数(SHEI)和分离度指数(SPL)的变化特征,明确林内色彩斑块景观指数对生态景观林美景度的影响,分析不同林分景观质量的差异性,进而为生态景观林经营与评价提供依据。主要研究结果如下:(1)白桦纯林斑块多样性指数最高,美景度与斑块多样性指数呈显著负相关(相关系数为-0.847),导致白桦纯林美景度最低,且与其他3个林分类型差异显著;低密度落叶松纯林美景度最高,人们对落叶松纯林喜好程度较高。(2)美景度与色彩斑块LSI值存在正相关性,...  相似文献

Widespread and increasing urbanization has resulted in the need to assess, monitor, and understand its effects on stream water quality. Identifying relations between stream ecological condition and urban intensity indicators such as impervious surface provides important, but insufficient information to effectively address planning and management needs in such areas. In this study we investigate those specific landscape metrics which are functionally linked to indicators of stream ecological condition, and in particular, identify those characteristics that exacerbate or mitigate changes in ecological condition over and above impervious surface. The approach used addresses challenges associated with redundancy of landscape metrics, and links landscape pattern and composition to an indicator of stream ecological condition across a broad area of the eastern United States. Macroinvertebrate samples were collected during 2000–2001 from forty-two sites in the Delaware River Basin, and landscape data of high spatial and thematic resolution were obtained from photointerpretation of 1999 imagery. An ordination-derived ‘biotic score’ was positively correlated with assemblage tolerance, and with urban-related chemical characteristics such as chloride concentration and an index of potential pesticide toxicity. Impervious surface explained 56% of the variation in biotic score, but the variation explained increased to as high as 83% with the incorporation of a second land use, cover, or configuration metric at catchment or riparian scales. These include land use class-specific cover metrics such as percent of urban land with tree cover, forest fragmentation metrics such as aggregation index, riparian metrics such as percent tree cover, and metrics related to urban aggregation. Study results indicate that these metrics will be important to monitor in urbanizing areas in addition to impervious surface.  相似文献

To establish a quality evaluation system of the fruit quality of pear, 15 evaluation indicators of 9 main cultivars of pear (Pyrus spp.) in North China were analyzed. Analysis of variance (ANOVA), correlation analysis (CA), principal component analysis (PCA) and hierarchical cluster analysis (HCA) were used to form a comprehensive evaluation model and select the characteristic indicators of the fruit quality. All of the 15 evaluation indicators showed significant differences from the results of ANOVA (P?<?0.05) among different cultivars. The values for coefficient of variation (CV) among 15 evaluation indicators ranged from 1.46% to 326.38%. There were different degrees of correlations between the evaluation indicators based on the results of CA. PCA was used to remove the overlapped information between the indicators, and then there were new variables with less information, so that the principal component comprehensive model was established. The rank of the 9 cultivars based on comprehensive scores of the fruit quality was listed as follows: ‘Mili’?>?‘Xuehua’?>?‘Hongxiangsu’?>?‘Daguoxing’?>?‘Yali’?>?‘Huangguan’?>?‘Yuluxiang’?>?‘Hongxiaoli’?>?‘Anli’. By combining HCA and principal component comprehensive model, titratable acid content, sugar-acid ratio, h* and fruit shape index were selected to be the characteristic indicators for the evaluation of the fruit quality of the main cultivars of pear in North China.

In urbanising landscapes, planning for sustainable biodiversity occurs in a context of multifunctional land use. Important conditions for species persistence are habitat quality, the amount and configuration of habitat and the permeability of the landscape matrix. For planning purposes, these determinants should be integrated into simple indicators for spatial conditions of persistence probability. We propose a framework of three related indices. The cohesion index is based on the ecology of metapopulations in a habitat network. We discuss how an indicator for species persistence in such a network could be developed. To translate this network index into an area index, we propose the concept of spatial cohesion. Habitat cohesion and spatial cohesion are defined and measured for single species or, at best, for species profiles. Since species differ in their perception of the same landscape, different species will rate different values of these indices for the same landscape. Because landscapes are rarely planned for single species, we further propose the index of landscape cohesion, which integrates the spatial cohesion indices of different species. Indices based on these concepts can be built into GIS tools for landscape assessment. We illustrate different applications of these indices, and emphasise the distinction between ecological and political decisions in developing and applying such tools. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献
