一、当前城市园林绿化建设中存在的一些问题(一)城市园林绿化设计中的问题城市园林绿化的植物景观是园林绿化设计者“设计理念”的最终体现,在设计中,最重要的是园林植物的配植设计。但设计者往往为了追求即时视觉效果,没有充分考虑后期生长稳定性及养护成本,对园林地形、水体、建筑、小品、铺装等方面的景观设计十分注重  相似文献

下文结合作者多年建筑设计工作经验,阐述了现代城市良好居住环境的宏观控制策略,并从高层建筑的规划和高层小区经济效益、环境效益和社会效益结合起来。由于建筑设计者受条件限制(用地问题、造价问题等)往往不会考虑建筑与城市的关系。因此,探讨在高层建筑设计中做到与城市空间的整合是有必要的。  相似文献

消防工程的设计是源头,一是设计者整体素质的好坏及执行、理解规范的精准度,这就要求建立消防工程专业设计考评,颁证、注册制及设计者内部把关制,并建立设计单位资格的分级注册制;二是把好设计审查关,在现有审、验分离制基础上,应从根本加以解决审、验的主体资格分离问题,将职责分离,分别从技术关和管理关双重人手(规范和执法),真正体现审验权威性、  相似文献

The bio-control potential of rhizospere bacteria Pseudomonas fluorescens against plant-parasite nematode had been demonstrated. P. fluorescens had shown the effect to enhance tobacco resistance to root-knot nematode Meloidogyne incognita. Inoculation with P. fluoreseens in tobacco could lead to significant reductions in the number of juveniles that penetrated tobacco root and further life stage development of the juveniles. The number of juveniles penetrated into tobac- co root in treatment with P. fluorescens is significantly different from CK at 2DAI, 6DAI, 8DAI and 10DAI. Significant reduction and delayed development of juveniles that penetrated into tobacco root and treated were observed in treatment at 14DAI, 21DAI, 28DAI and 35DAI. In addition, P. fluoreseens treatment leads to a significant reduction in the number of eggs per egg-mass at 35 DAI. The results show P. fluorescens induced a continuously suppression on root-knot nema- tode M. incognita throughout their entire early infection phase of root penetration, subsequent life stage development and reproduction.  相似文献

This paper quantifies the local impacts of mechanized logging on forest-dependent communities in Indonesia, before and after decentralization. A conceptual framework incorporates financial, social, enforcement, rent-seeking, and environmental impacts. Using data from 60 communities in East Kalimantan, the empirical results suggest that significantly more households received financial and in-kind benefits after decentralization compared to before. Many communities engaged in self-enforcement activities against firms both before and after decentralization. Post-decentralization, a significantly higher proportion of households perceived community forest ownership. There were few significant differences in perceived environmental impacts. Little evidence exists of a post-decentralization trade-off between environmental and financial contractual provisions.  相似文献

Zusammenfassung Die vorliegende Studie analysiert für 87 Neuprodukteinführungen (NPE) und Auslandsmarkteintritte (AME) von Telekommunikations(TK)-Diensteanbietern in Deutschland, zu denen 42 Schlüsselinformanten in einer schriftlichen Befragung Auskunft gaben, (1) inwieweit deren zeitliche Eintrittspositionierung durch Marktcharakteristika und Unternehmensressourcen erkl?rbar ist sowie (2) inwieweit und gegebenenfalls unter welchen unternehmensexternen und -internen Situationsbedingungen deren Markteintrittstiming mit dem wahrgenommenen Eintrittserfolg assoziiert ist. Ein früher Markteintritt wurde dann realisiert, wenn die Wettbewerbsintensit?t im adressierten Gesch?ft niedrig und das Budget für den Expansionsschritt überdurchschnittlich ausfielen. Zwischen dem Markteintrittstiming und der Beurteilung des Eintrittserfolgs bestand ein nicht monotoner, umgekehrt U-f?rmiger Zusammenhang: Frühe Folger wiesen signifikant bessere Erfolgswerte auf als Pioniere und sp?te Folger, deren Erfolgsniveaus nicht signifikant divergierten. In einer Industrie, die durch starke externe Netzeffekte gepr?gt ist, fallen offenbar die Nachteile eines Markteintritts als Pionier oder sp?ter Folger st?rker ins Gewicht als die Vorteile dieser beiden zeitlichen Eintrittspositionierungen. Unabh?ngig vom Markteintrittstiming wurden NPE/AME von TK-Unternehmen als erfolgreicher eingestuft, wenn sie sich in einen Markt mit stark wachsender Nachfrage und aufeinander abgestimmt (re)agierenden Wettbewerbern mit qualitativ überdurchschnittlichen, abw?rtskompatiblen, erprobbaren und wenig erkl?rungsbedürftigen TK-Diensten engagierten.   相似文献

Indonesia’s economic growth picked up slightly in mid-2016 but remains below the level demanded by government and popular aspirations. Despite a plethora of reforms intended to increase efficiency and productivity, some policies are perverse and longstanding problems of implementation remain. The share of manufacturing has declined, the real exchange rate has appreciated, exports have dwindled, and growth has been trending downwards. The banking sector is stable but inefficient, with wide net interest margins and numerous barriers to competition. Trade protection, particularly in basic food commodities, has created high costs that weigh particularly heavily on the poor. Declining government revenues have placed increasing pressure on the public budget, even as the current administration aims to increase spending on infrastructure and welfare and to enhance productivity. In an effort to increase revenues, the government has announced a tax amnesty program and other measures. In addition, Sri Mulyani Indrawati, the new finance minister, has taken steps to cut non-essential expenditure in order to secure high spending on infrastructure and at the same time keep within the 3% budget deficit limit stipulated by law. Although the overall debt situation is not yet alarming, declining revenues and budget cuts that do not fully reflect this decline are putting pressure on increasing debt levels. The government’s high-profile tax amnesty program was the major policy initiative implemented in the second half of 2016 that aimed to relieve this pressure. Despite widespread criticism of, and scepticism about, the tax amnesty (both within and outside Indonesia), its first phase had a much higher participation rate than most independent accounts expected. Revenues raised so far through the amnesty are less than 60% of the official target, but this is actually a strong result for the short term. The bigger question, however, is whether the amnesty is a key element of a more encompassing strategy to overhaul the system of taxation and tax administration.  相似文献

In this paper, I analyze the causes of the prolonged slowdown of the Japanese economy in the 1990s and find that the stagnation of investment, especially private fixed investment, was the primary culprit. I then investigate the causes of the stagnation of household consumption during the 1990s and find that the stagnation of household disposable income, the decline in household wealth, and increased uncertainty about the future are among the contributing factors. Finally, I consider whether demand side factors or supply side factors were more important as causes of the prolonged slowdown of the Japanese economy in the 1990s and conclude that the former (especially misguided government policies) were probably more important.  相似文献
