Study on Planning and Design Mode of Eco-agricultural Demonstration Base in Poyang Lake Eco-economic Zone

Guided by the Planning of Poyang Lake Eco-economic Zone, traffic and geographic conditions of the Eco-agricultural Demonstration Base in the study area were analyzed, and design principles proposed as "adaptation to local conditions, scientific planning, benign circulation and sustainable development". Detailed planning and design was interpreted from the perspectives of infrastructure planning and functional area planning. Specifically, infrastructure construction should focus on traffic design, water, power and gas supply design, and also architectural design; while functional areas should be gradually developed from south section to central and then north section. It was to establish a design and planning mode that can be widely applied.

Spatio-temporal difference analysis of cultivated land use intensity based on emergy in the Poyang Lake Eco-economic Zone of China

Taking the emergy requirements of the five input indexes as the foundation, this paper analyzes the total temporal and spatial changes in cultivated land use intensity in the Poyang Lake Eco-economic Zone from 2000 to 2010. The results are obtained as follows： （1） Over a period of 10 years, the cultivated land use intensity has increased exponentially in the Poyang Lake Eco-economic Zone; agricultural machinery intensity has been the largest proportion of the total inputs, comprising more than 99.50% and increasing year by year, which indicates that agricultural mechanization is a basic trend in agricultural development in the Poyang Lake Eco-economic Zone. （2） The total number of counties belonging to the moderate- and low- intensity cultivated land use categories is the largest, while the number of counties belonging to the high-intensity cultivated land use and extensive cultivated land use categories is the smallest. （3） This zone can be divided into five areas： an eastern area of high-intensity cultivated land use, a central and eastern area of low-intensity cultivated land use, a central area of low-intensity cultivated land use, a southern area of moderate-intensity cultivated land use, and a northern area of moderate-intensity cultivated land use. （4） The counties which had a coordinated development between cultivated land use intensity and their socio-economic development level increase year by year, and the socio-economic development level had increasingly obvious effects on the cultivated land use intensity. Finally, this paper presents suggestions for the development of cultivated land use intensity in the Poyang Lake Eco-economic Zone, especially for different levels of intensity among counties.

Sustainable Livelihood Security in the Poyang Lake Eco-economic Zone:Ecologically Secure,Economically Efficient or Socially Equitable?

Sustainable Livelihood Security(SLS)remains a rarely considered yet important issue for rural sustainability and natural resource management.Particularly in China,rural SLS research in a typical area is urgently needed,but insufficient under the background of National Rural Revitalization and Ten-year Fishing Ban of Yangtze River.Focusing on the policy-targeted inland lake area,we proposed a Livelihood Security Analysis(LSA)framework by establishing an adaptive indicator system and integrating multiple econometrical and geographical methods.This study aims to evaluate the SLS in Poyang Lake Eco-economic Zone comprehensively from the three aspects of ecology,economy and society,analyze their spatial patterns,identify the main constraints,and finally give specific suggestions for improving rural sustainability management.The results showed that rural SLS in the inland great lake area tended to be vulnerable mainly due to the lagging economic efficiency and unbalanced social equality,and mediated by regional ecological characteristics.The overall SLS and Ecological Security Index(ESI)were higher in the north and lower in the south,while Economic Efficiency Index(EEI)and Social Equality Index(SEI)were at the middle level and circularly distributed around Nanchang City.The dominating factors which have greatly shaped the spatial pattern of SLS include rural per capita electricity consumption,fishery breeding area,population dependency ratio,urbanization rate,and fishery population.The obstacle degree is ranked as economic system>social system>ecological system.An outdated economy and incomplete social services are the main constraints,characterized by weak electricity consumption,limited beds in hospitals,low urbanization rate,deficient agricultural machinery power,and a small agricultural output value.Therefore,one urgent need is to activate the rural economy by reinforcing rural electric power facilities and promoting agricultural mechanization.In addition,transforming the peasants/fishermen to the non-agricultural sector should be accelerated,which will help to reduce ecological pressure,boost urban-rural integration and narrow the income gap.

基于主体功能区的土地利用分区研究——以环鄱阳湖区为例

在主体功能分区基础上,对环鄱阳湖区进行土地利用分区,以实现空间有序发展和土地利用的差异化管理,为区域可持续发展提供土地保障。根据环鄱阳湖区主体功能分区图、土地利用现状图、土地适宜性评价结果图,在ArcGIS9.2中进行叠置分析和空间聚类分析,通过制定基于主体功能区的土地利用分区属性赋值规则,得到环鄱阳湖区土地利用分区图。在土地利用政策层面协调主体功能分区和土地利用分区的基础上,将环鄱阳湖区划为农业用地区、生态林用地区、城镇及工业用地区和湿地保护区,并提出了相应的土地用途管制措施。

鄱阳湖及周边经济区种植业区划

种植业区划是为了当地种植业的发展,使当地种植业适应农业现代化的发展要求,并适当增加当地农民的收入。收集了鄱阳湖及周边经济区29个县、市、区种植业方面2005年的数据,选取11个指标作为区划指标,用DPS软件进行系统聚类,用Arc View GIS3.2软件形成区划地图。最后鄱阳湖及周边经济区种植业共分为4个区,即:(1)中部、东北部洼地、平原、山地粮食作物种植区;(2)西南、中部山地、丘陵粮食、油料作物种植区;(3)西北、北部山地、洼地棉花、油菜种植区;(4)东南、东北部丘陵、平原粮食兼油菜、糖料、蔬菜作物种植区。通过区划,对当地种植业的发展有一定的指导作用。

鄱阳湖生态经济区产业规划与城市定位研究

选取相关指标,采用熵权灰色关联模型评价鄱阳湖生态经济区六市的三大产业。结果表明:鄱阳湖生态经济区三大产业地区间发展失衡现象较为严重。单独而言,第一产业基础较好,但生产水平较低;第二产业效率尚可,但整体规模较小;第三产业发展一般,旅游业的核心作用日益凸显。比较分析鄱阳湖六市可见,南昌、九江的三大产业发展比较均衡,整体水平处第一层次;景德镇、鹰潭、抚州、新余四市除抚州在第一产业得分最高之外,其他得分都比较接近,与南昌、九江存在较大的差距。故应以生态环境保护和可持续发展为前提,积极发展现代农业、特色养殖业和苗木业;协调工业有序发展,避免同质竞争;大力推进旅游业,带动相关产业发展。同时提升南昌、九江的核心竞争力,发挥其区域中心城市的作用,带动整个鄱阳湖生态经济区快速发展;景德镇、鹰潭、抚州、新余四市应依托现有的优势资源,发展特色产业。
