The classification system of backbone forest strip types had been put forward according to the landform type,strong or weak sea wind,microtopography,forest tree growth,forest strip structure feature and windproof efficacy by means of the typical survey of backbone forest strips for \%Casuarina equisetifolia\% in the coastal draught,the mobile observation of windproof efficacy and the serial researches of regeneration afforestation technigues on Chishan Forest Farm,Dongshan County and Chihu Forest Farm,Hui′an County both in Fujian Province since 1992.The local forest belts were classified into 9 main types and the backbone forest strip classification regeneration theory was advanced accordingly.The breakthrough of backbone forest strip classification theory research brought along the constant innovation in the forest strip regeneration modes and afforestation techniques and energetically promoted the smooth development of backbone forest strip regeneration afforestation in \%C.equisetifolia.\%In respect of forest strip regeneration modes,according to the different\|type forest strip regeneration afforestation research result,the alternate strip and planting under canopy within strips and the thinning interplanting regeneration mode were put forward,as well as various key techniques,including regeneration strip width control,crown density control and thinning intensity were adopted. Based on the combinative principle of tree species adaptability,fast growth and protective function,some regeneration afforestation tree species were raised for different\|type forest strips,such as \%Acacia crassicarpa,A.aulacocarpa,Eucalyptus ABL No.12, Pinus elliottii\% and \%C.equisetifolia\% excellent clones.More than 7 million plants of these excellent tree species and clones had been bred and were popularized for afforestation in the adjacent cities and counties in succession.In respect of key techniques for forest strip regeneration afforestation,the serial drought\|resistant afforestation techniques of digging deep holes for site preparation,putting into the proper earth removed from other places,applying phosphoric fertilizer,mixing mud,selecting rainy days for afforestation in spring,planting deeply with big container\|growing seedlings,and ridging tending for preserving the soil moisture in young forests were put forward for the poor habitat conditions of gales,drought,soil being deficient water and poor,etc.in autumn and winter,and the planting survival percent of most tree species reached 90% or so.The average height of main planting tree species of 3\|year\|old young forests was 3~5m,which had become closed forests and began to give full play to protection.Thus the relative wind speed within regeneration forest strips was about 10% less than that before planting.This is one of the great breakthroughs of regeneration technique researches of backbone forest strips for \%C.equisetifolia\% in the coastal draught.These techniques have been accepted and universally adopted by the local forestry productive units.

Urban regeneration is a natural outcome of urbanization. Since the beginning of 1950s in last century, urban development conception in western countries has changed 5 times so far from urban reconstruction in 1950s to urban revitalization in 1960s, urban renewal in 1970s, urban redevelopment in 1980s, urban regeneration in 1990s. Each concept represented very rich contents of that time, and was well substituted the before by the behind. A mass scale urban reconstruction in China was initiated just after the People's Republic of China was found in 1949, but the great achievement has been reached in the last 20 years when "the reform and opening policy" was in operation successfully, which includes both the practical experiences and the theory introduced and utilized in practice such as " urban organic regeneration theory". It is reasonable to believe that all the large cities in the whole country will unavoidably march on the road of regeneration in 21st century, so far as the urban regeneration is an intension and quality oriented policy to take. In the regeneration process, China is going to dell with 5 respects issues such as deindustrialization and tertiarisation in the big cities industrialized cities, suburbanization and gentrification particularly in regional central cities, community construction and employment as one aspect of countermeasures for providing more jobs, urban historic and cultural heritage protection and utilization as one important sector for developing tertiary, urban regeneration legislation and planning and management which is needed to be enhanced part in urban regeneration activity.

城市再生是城市化深化的必然结果。20世纪50年代以来,西方城市开发概念经历了5次变化,即城市重建、城市振兴、城市更新、城市再开发和城市再生。每一概念都包含丰富的时代内涵,并具有连续性。我国大规模的城市更新改造是从新中国成立以后开始的,特别是改革开放20多年的开发建设取得了巨大成绩。在实践上积累了宝贵的经验和深刻的教训,在理论上引借了“城市有机更新论”。21世纪我国大城市都不可避免地要踏上城市再生之路,城市再生是新世纪内涵式、质量型城市化政策的必然选择。我国城市再生在实践和理论上面临的5个方面的重要问题,即“逆工业化”和“第三产业化”、“郊区化”与“中产阶层化”、城市社区建设与就业、城市历史文化保护和利用以及城市再生的法制建设、规划和管理。

Northeast China is a typical old industrial area with high urbanization level in China. There are 90 cities in 2000, and urbanization level is 46.55%, which is around 10 percent higher than the average level of the whole country. However, since 1978, the area has experienced a tough reconstruction process. Regional development lagged behind in respect to southeast coastal area, and the rate of urbanization slowed down, urbanization quality was low. Due to the decline of traditional industries, regional urbanization was encountered with all problems such as state owned enterprises reform, unemployment and laid-off workers, transformation of the resources-exhausted cities, and eco-environmental quality degradation etc., hence to quicken the pace of urbanization and improve urbanization quality becomes a key way in revitalizing the old industrial base. According to the current situation, regional urbanization tendency, characteristics of the declining area, and related urban regeneration theories, the authors put forward a new urbanization strategy for the old industrial base. The overall object is to reconstruct Northeast China into a modern settlement system with prosperous economy, advanced cultural society, beautiful physical environment, clear urban function, reasonable distribution and coordinating structure of different sized cities. The general layout is to establish 4 megalopolises centered by Dalian, Shenyang, Changchun and Harbin, which have the potential to form a huge megalopolis along the key traffic axis from Harbin to Dalian. There are 6 key aspects for carrying out the new urbanization strategy, which are transforming economic structure of the resources exploiting city, regenerating the old industrial zone inside big city, improving industrial agglomeration and reorganizing industries among the megalopolises, rural urbanization, accelerating urban informationization, renovating urban environment and renewing urban ecology. The authors give an in-depth analysis on the existing problems in relation to the above aspects and bring forward main countermeasures.

依据东北地区城市化现状特点、问题、趋势和城市化相关理论,提出振兴东北老工业基地要采取与新型工业化战略相适应的新型城市化战略。该战略的总体目标是把东北老工业基地建设成现代化的人居环境系统,构建“三圈一带”为主的空间骨架。从资源型城市经济转型、大城市老工业区改造、大都市圈产业集聚与空间重组、乡村城镇化、城市信息化和城市生态环境整治与人居环境建设6个方面论述了新型城市化的战略重点及其对策。
