Form feature of farmland ecosystem and ecological security angle of the region set out, analyzing affection of farmland landscape pattern to ecological environment, bring to light that spatial heterogeneity and fragmented of farmland landscape pattern are important influence factor to land ecological environment security in the farming stock-raising in this paper 从区域农田生态系统特点和地区土地生态安全角度出发,通过对市域农田景观空间格局特征及其对土地生态环境安全影响的分析,显示出农田景观格局的空间差异性与破碎度高是农牧交错地区土地生态环境安全的重要影响因素。
Both oxyopes sertatus and harpactor fuscipes are important predators of common cutworm ( spodoptera litura ) on tobacco . the effect of several interference factors on the predations of o . sertatus and h . fuscipes on the larvae of s . litura were examined in laboratory . the results indicated that there were significant mutual interferences on their predations with the existence of other individual in the same / different species . as the number of the predator increased, the predation rates decreased significantly . the interference coefficients ( m ) within h . fuscipes and within o . sertatus were 0.7278 and 0.6911, respectively, while the interference coefficient ( m ) between o . sertatus and h . fuscipes was 0.9464 . these results showed that the effect of mutual interference on predation in interspecies was more obvious than that in intraspecies . the number of prey captured and the predation rate of predator dropped with increasing the number of tobacco stalks . this result suggested that spatial heterogeneity was also an important factor affecting the predation of predator on prey 斜纹猫蛛和红彩真猎蝽均是烟草上斜纹夜蛾的重要捕食性天敌.室内测定几种干扰因素对斜纹猫蛛和红彩真猎蝽捕食作用的影响,结果表明这些干扰因素对斜纹猫蛛种内、红彩真猎蝽种内和两种捕食者种间的捕食作用均有明显的干扰作用,随捕食者数量的增加,其对斜纹夜蛾捕食作用率显著降低.斜纹猫蛛种内的干扰系数和红彩真猎蝽种内的干扰系数分别为0.7278和0.6911,而两者种间的干扰系数为0.9464,说明两者种间的干扰作用要明显高于同一种捕食者种内的干扰作用.两种捕食性天敌对斜纹夜蛾的捕食量和捕食作用率随烟草茎杆数的增加而降低,表明空间异质性同样是影响两种捕食性天敌捕食作用的一个重要因素
Sustainable tourism development of regional culture landscapes, not only comprises one important area of culture landscapes studies, but also is vital to realize tourism sustainability . the essence of sustainable tourism development of regional culture landscapes is constructing spatial heterogeneity and dynamically improving its function of landscape system . with the case study of shaoxing city, the authors apply the theories and methods of lands cape ecology to sustainable tourism development of shaoxing culture landscapes . there are three main aspects emphasized : to conserve and reasonably develop unit culture landscape; to construct spatial heterogeneity and improve its function; and to put forward suggestions for macro-ecological management of shaoxing culture landscapes 区域文化景观旅游可持续开发的实质,就是其地域内空间异质性的不断构建与生态整体性的动态维持。本文以绍兴市为例,尝试将景观生态学的有关理论和方法,贯彻到区域文化景观的旅游持续开发中。强调要在以下3个层面上展开:首先,保护和合理利用文化景观的个体单元其次,构建文化景观的空间异质性格局以及维护和改善其功能最后,提出绍兴文化景观宏观生态管理的对策措施。
