A comparison between different ecological de-farming modes in the loess hilly-gully region in China

The eco-environmental restoration has been a chief task of the western development strategies carried out by the central and local governments of China since the late 1990s, and the ecological de-farming has been regarded as a powerful measure for the ecological restoration in the Loess Plateau and the upper reaches of the Yangtze River. "Relieving and de-farming" (RD) and "rebuilding terrace and de-farming" (RTD) are two more mature ones among various de-farming modes. Taking the loess hilly-gully region as a case, this paper summarized the basic characteristics of RD and RTD modes, calculated the sizes of de-farming slope farmland, rebuilt terraces, enlarged garden plots and restored vegetation, and compared the differences of two modes in terms of de-farming area, ecological reestablishment index, investment demand amount and benefits. The results showed that RTD mode has many advantages, including suitable investment, sufficient grain supply and great benefits, and will be the best ecological reestablishment mode in the loess hilly-gully region, and RD mode which is being carried out in this region should be replaced by RTD mode as soon as possible.

The Theoretical Explanation of Non-ecological Economic Qualities of the Development Mode of Industrial Civilization:An Analysis Based on the Critical Perspective

The development mode of industrial civilization has created huge material wealth for human society,but at the same time the severe ecological problems that have arisen from it have made human civilization fall into the dispersion of unsustainable development.The industrialized development mode has obvious non-ecological economic qualities,which are specifically manifested in the destruction of the ecological economy relationship between nature and mankind,the emergence of cracks of metabolism between nature and mankind,the unbalanced development of the social productive forces and the natural productive forces,and the functioning of one-way linear non-circular economy.Under the trend of ecological evolution of human civilization,the industrial civilization will be replaced by the ecological civilization,and then the industrial economic development mode will be transformed into the ecological economic development mode.As a result,the predicament of once unsustainable development has been gradually dispersed and human civilization enters a beautiful new era of coordinated development of economic society and natural ecology.

On the Ecological Restoration Mode of Urban Water Revetment Landscape

Urban waterfront revetment is a special zone between water and land,with high ecological,economic and aesthetic value. Waterfront revetment landscape is not only an important part of urban water and land ecosystems,but also an integral part of the city. Based on the current situation of ecological environment of waterfront revetment landscape,we come up with different ecological restoration modes for different types of revetment,to achieve the organic integration of waterfront revetment landscape and ecology.

A study of economic development in Tibet of China based on the ecological economic mode

The purpose of this paper is to study the issues on keeping the continuous development of Tibetan economy and the relative stability of its ecosystem. Hence, in order to achieve the object, the study analyzes the status quo of economic development in Tibet and the problems of resource exploitation. It especially discusses frailty of Tibetan eco- environment, and evaluates the contradictions between the traditional economic developing mode and the safety of plateau’s ecosystem. It concludes that there is an inevitable clash between the development of Tibetan economy and the safety of plateau’s eco-system; this problem cannot be avoided by any decision maker. Therefore, the character of Tibetan eco-environment and the requirement of its economic development strategy determine that ecological economy develop- ing mode is the only choice for Tibet. This paper suggests that it should be compensated by the national government to assure that Tibetan economy can keep a higher developing speed. In accordance with the feature of plateau eco-economy system and demand of Tibetan economic development, this paper also suggests several methods to apply the eco- economy developing strategy of Tibet.

Rational Reflection and Realistic Transcendence on Ecological Crisis: Based on the Perspective of Marxist Ecological Concept

The construction of ecological civilization fully demonstrates the CPC's historical initiative spirit to keep pace with the times. This ruling mind is rooted not only in the realistic interpretation of Marxism ecological view,but also in the profound introspection on the development of history of human civilization. It has a practical guiding meaning to the construction of socialism with Chinese characteristics. Furthermore,it has a theoretical perspective on the ecological crisis which is a global problem. Therefore,we should stand on the commanding heights of humanity's horizons,and restore systematically the harmonious relationship between man and nature from the perspective of ecological aesthetics.

Development of Ecological Fishery in Poyang Lake Area

Through in-depth analysis on history and current situations of fishery development in Poyang Lake area,this paper presents location,resource and environment advantages in development of ecological fishery.According to orientation of leading functions,Poyang Lake can be divided into breeding development,capture operation,enhancement protection and ecological rehabilitation functional zones.In accordance with industrial foundation and ecological advantages of cities and counties in Poyang Lake,it determines the reasonable distribution of 8 leading industries:river crabs,shrimps(Procambarus clarkia),eels,Pengze crucian carp,Siniperca chuatsi,Channa argus,Ietalurus Punetaus,and pearl.On the basis of systematically summing up exploration experience,it comes up with the development path"ecology oriented fishery and industrialization oriented ecological fishery"for ecological fishery in Poyang Lake area.It proposes a series of key technological measures,including reducing fertilizer and drugs,increasing output and benefits,low consumption and emission,high quality and safety,and standardization,to realize a benign cycle of"cost saving,benefit increasing,quality improving and low carbon"and the multi-win objective of coordination between ecology,economy and society.

Evolution paths of green economy modes and their trend of hypercycle economy

So far there is a lack of specialized research on the entire path and the law of the evolution of green economy modes,especially studies on its future trend.Some studies have been done only on its sub-process,in which there are some shortcomings such as overlapping and incomplete classification of economy modes,as well as the lack of mechanism models to describe the modes.This paper attempts to solve those problems.Firstly,various green economy modes are extracted and classified,and then their evolution paths are identified and reviewed,according to sustainable development theory,hypercycle theory,etc.,and to practical investigation.Secondly,theoretical models for each green economy mode and their multilevel dynamic evolution models in a practical field(forestry as an example)are established by the modeling method of system structure.Finally,the evolution law of green economy mode is analyzed systematically by means of the above-mentioned models.According to the research,some conclusions are drawn as follows:First,green economy modes have evolved through three stages as a whole.The first is the start-up stage,in which the mode is the‘from cradle to grave’end-treatment green economy(GE-I).The second is the growth stage,in which the mode is the‘from cradle to cradle’resources-chain closed-loop green economy(GE-Ⅱ).The third is the mature stage,in which the mode will be the‘from breeding to breeding‘three-chain hypercycle economy(GE-Ⅲ).Second,GEⅡhas evolved through a specific process.In depth,the basic framework of GEⅡis based on the circular economy theory;and then it is combined gradually with some other relevant theories and technologies that are cleaner production,low-carbon economy and sharing economy and so on.In breadth,GE-Ⅱis expanded layer by layer from unified enterprise GE-Ⅱto diversified enterprise(or cluster)GE-Ⅱ,and to societal GE-Ⅱ.The operational principle of GE-Ⅱcan be described by 3R theoretical model that includes 3 subsystems of reduction,recycle and reuse(3R),which are connected into an organic whole by resources chain.Third,GE-Ⅲis evolving through a specific process of three-chain(3C)stage by stage expansion,from resources-chain primary hypercycle to eco-chain secondary hypercycle,and to value-chain tertiary hypercycle.The operational principle of GE-Ⅲcan be described by 5R-3C theoretical model that includes 5 subsystems of reduction,recycle,reuse,recultivation and reallocation(5R),which are connected into an environment-economy self organizing system by resources chain,ecochain and value chain.In the system,resources chain is the foundation,eco-chain is the support,and value chain is the impetus.The 3C hypercycle promotes and catalyze each other to realize mutualism between ecosystem and industrial system.Fourth,the related field of GEⅢincludes the principal part of renewable-resource-based industry,and the expanded part of other relevant industries and even the whole society.Now in practice,GE-Ⅲhas initially formed.And in the future,it is the development tendency of green economy toward the establishment of the ecological civilization.

Spatiotemporal analysis and multiple scenarios prediction of sustainable ecosystem in China based on ecological footprint method

Dynamic changes of sustainable ecosystem in China have been assessed with long-term series from 1949 to 2006, and the ecosystem sustainability of 30 provinces in 1986, 1996, 2002 and 2006 are analyzed with ecological footprint index (EFI) and ecological footprint efficiency (EFE). The two indices are proposed based on ecological footprint (EF) method. Then, the fluctuant cycles of per capita EF and bicapacity (BC) in China 1949-2006 are decomposed and extracted based on EMD method, and series nonlinear dynamic predictive models are presented with the cycles. Three Forecasting scenarios are analyzed based on their predictive models according to three EF scenarios presented in Living Planet Report 2006 published by WWF et al.(2006). Over last 57 years, China’s EFI has reduced sharply with fluctuation. The change of EFE is very slowly before 1980, subsequently, is sharply increased. There are 6, 5, 12, and 7 provinces which are running ecological surplus in 1986, 1996, 2002, and 2006, respectively. There are 14, 16, 11, and 16 provinces which EFI are smaller than -100% in 1986, 1996, 2002, and 2006, respectively. The provinces with the highest EFE are Shanghai, Beijing, and Tianjin, and the lowest are Xinjiang, Guizhou, Hainan, Ningxia, et al. in 1986, 1996, 2002, and 2006, respectively. The obvious undulation cycles of per capita EF in China are 4.8 years and 10.9 years, and the periods of per capita BC are 3.03 years, 8.35 years, 14.25 years, and 28.15 years. The business-as-usual scenario looks at the consequence that per capita ED would be 11.200hm2 and EFI would be -1307.19% in China in 2050. The slow-shift scenario shows per capita ED would be 0.728hm2 and EFI would be -84.96% in 2050. The rapid-reduce scenario shows per capita ED in China would be 0.498hm2 in 2050 and 0.261hm2 in 2100, respectively. EFI of rapid-reduce scenario would be -58.11% in 2050. China could denote sustainability at the global level if slow-shift scenario and rapid-reduce scenario are implemented.

Ecological Significance in Marx's Theory of Metabolic Rift and Targeted Poverty Alleviation in Rural Areas

In expounding the historical conditions of " two necessities",Marx profoundly criticized the consequence of capitalist mode of production to society and ecology. Through the analysis of the capitalist relations of production,Marx systematically completed the viewpoint system about the material circulation of nature and human society,and foresaw the ecological consequences of capitalism to the world scientifically,taking ecology and mode of production as an organic whole. Since the socialism with Chinese characteristics entered into the new era,facing the serious ecological problems in the countryside in the process of modernization,the Party and the state,through the latest interpretation of the basic principles of Marxism,have creatively replaced the unsustainable poverty-alleviation policy with the targeted poverty-alleviation policy,thus making it have an important ecological orientation in the practice of poverty-alleviation in the countryside.

Trends in per capita ecological footprint and biocapacity in China 1949-2013

This paper proposes two concepts: the ecological footprint component index(EFCI) and the biocapacity component index(BCCI), based on the ecological footprint(EF) and Shannon entropy approaches. Per capita EFCI and BCCI in China 1949-2013 are analyzed using empirical mode decomposition(EMD). Nonlinear models of per capita EFCI and BCCI in China 1949-2013 are presented and their cycles and predictions from 2014 to 2023 are analyzed. The results over the last 65 years show:(1) EFCI in China has increased constantly with fluctuations, while BCCI has slowly decreased. Their annual change rates are 2.81% and-1.26%, respectively. The increasing EFCI indicates a gradual improvement in China's sustainable development potential; the decreasing BCCI indicates severe environmental and population challenges.(2) The cycles of per capita EFCI have periods of 5.4 and 16.3 years, while cycles of per capita BCCI have periods of 3.6, 13,and 21.7 years. The predictive models indicate that EFCI will first decrease, reaching 0.02725 in2014, and will subsequently increase to 0.03261 in 2021. BCCI will increase, reaching 0.01365 in2014 and 0.01541 in 2022. EFCI and BCCI will reach 0.03037 and 0.01537, respectively, in 2023.Policymakers should ensure that the EFCI and BCCI increase in 2023.

生态环境法典的罪刑条款设置

“《刑法典》是环境刑法更好的归属”的观点,只是一种主观判断,不一定符合事实;我国清末以来的刑法典都预设了多元刑事立法模式,单一刑法典模式不是由刑法典自身形成的,而是由于其他法律不设置罪刑条款形成的,生态环境法典应当直接设置环境犯罪的罪刑条款;罪刑条款应当与行为规则、行政处罚条款密切接近,故应采取分散型设置方式;行政刑法的特点是通过补强行为规则,确保行为规则的有效性,故生态环境法典中的罪刑条款通常采取行政犯的表述方式,但部分条款也可以采取刑法犯的表述方式;罪刑条款应以行政处罚条款为基础,通过增加不法要素与责任要素的方式,使环境犯罪具备应受刑罚处罚性;处理行政处罚与刑罚处罚的关系时,重在防止以刑罚处罚替代行政处罚;应当将行为人积极履行《民法典》规定的“修复生态环境责任”,规定为环境犯罪的减免处罚事由;生态环境法典中的罪刑条款设置应注重必要性、明确性、合理性、协调性,不必顾虑与现行刑法典中环境犯罪条款的重复与交叉。

基于SWOT分析的矿山生态修复治理EOD模式研究

矿山的生态修复治理已成为亟需解决的生态环境和区域协调发展的关键难题。本文系统分析了政府和社会资本合作模式(Public-Private-Partnership,PPP模式)及工程总承包模式(Engineering-Procurement-Construction,EPC模式)在矿山生态修复治理中的现状,并基于SWOT分析法梳理出生态环境导向的矿山生态修复治理开发模式(Eco-environment-oriented Development,EOD模式)下矿山修复的内在优劣势和外部的机遇与挑战。研究结果表明,EOD模式可以很好地吸纳EPC模式和PPP模式的优点,将矿山修复工作融合到区域经济发展中,EOD模式的优势表现在促进区域融合发展、加速土地指标流转、废弃资源综合利用、经济增长与环境保护相协调、缓解政府治理环境的压力、国家部门政策支持,以及环境治理资金投入不断加大等方面。EOD模式在矿山生态修复治理方面的劣势主要表现为对于区位优势不突出的矿山难以起到很好的融资效果,进而实现经济效益,并且在利益分配方面也面临着尾矿处置权益边界不清晰和国家在生态修复过程中的制度缺陷等问题。
