There is great potential for agriculture in saline-alkali soil area in Songnen Plain, Northeast China. But the sustainable crop production in this area has been restricted by a few of main factors, such as less precipitation, h igher evaporation and frequent drought, high salinity and alkalinity, high excha ngeable sodium content and poor infiltration of the soil, and insufficiency and low availability in nutrition. It is also considered that there are a few of fav orable conditions for agricultural development in this region, such as sufficien t light and heat resources, rich ground water resources, plenty of manure produc ed by livestock, and so on. At the same time, scientific management and measurem ents have been employed; rational irrigation and drainage system has been establ ished; reclamation, amendment and fertilization of soil, and suitable strategies of cropping practices have been made for the sustainable development of agricul ture. Great progress has been made during 1996-2000. 展开更多

According to the contemporary ecosystem approach, the linkages of human actions with their environment have to be assessed in an integrative manner. The Driver-Pressure-State-Impact-Response (DPSIR) model is applied to identify and describe processes and interactions in human-environmental systems. An example application from a research project dealing with the development of sustainable management strategies for the agriculture in Jiangsu, China, illustrates the potentials and limitations of its sustainable development. The concept and indicators of ecological integrity are used to assess the indicators in the dimensions of DPSIR between 2003 and 2006. The main drivers included population growth which caused increasing demand for food, growing environmental demands, and rapidly decreasing of land and other natural resources. The main environmental problem was water pollution. The results show that in the dimension of driver, total grain output and agricultural land productivity both increased. Labor intensive agriculture has been promoted to increase agricultural land productivity. In the dimension of pressure, on the positive side, infrastructure got greatly improved, the input level such as total power of machinery, and level of fertilizer use increased, and level of pesticides use decreased, but on the negative side, cultivated land per capita and irrigation rate decreased, natural resources keep decreased. Environmental pollution indicators such as industrial wastewater discharge and acid rain rate increased in Jiangsu Province. In the aspect of state, ecosystem state was improved, plant coverage index increased, biological abundance index increased, fertilizer productivity increased, eco-environmental quality index increased, but land degradation index also increased. In the aspect of impact, output level increased, output efficiency enhanced, farmer's social economic benefit improved. In the aspect of response, social support was greatly improved, input for environmental governance increased. To assess the effects of environmental governance, Jiangsu government was successful to increase compliance rate of sulfur dioxide emissions, but not so efficient in compliance rate of industrial wastewater discharge. 展开更多

Ecological security is the main task and applied field of present geography, resources and environment sciences and ecology. Ecological security evaluation will efficiently promote ecological security and environmental construction in regional land use. In this thesis, the authors put forward the index system of ecological security evaluation in karst mountainous area on three aspects, the pressure of resources and eco-environment, the quality of resources and eco-environment, and the ability of environmental protection and ecological improvement. Using the evaluation method with single index, based on the case study ofDu'an Yao Autonomous County of Guangxi Zhuang Autonomous Region, the system of synthetic regionalization of ecological agricultural economy was formed, which includes three regions, south region with basic security and synthetic agricultural development, east region with critical security and agriculture, forestry, animal husbandry balanced development, mid-west and south region with ecological insecurity and compounded agriculture and forestry management. Meanwhile, for these regions, the countermeasures of sustainable agricultural development were pointed out, which provide the basis and example for ecological regulation and control of sustainable agricultural development in counties ofkarst mountainous area. 展开更多

Based on the provincial units evaluation, this paper makes an assessment forsustainable developing capability of the integrated agricultural regionalization in China. At first,an index system of agricultural sustainable development in China is built up, which includes 5supporting subsystems of agricultural resources, agricultural development, environment andecosystem, rural society, sciences-education and management. We selected 95 factors on provinciallevel as basic indexes. Second, a relative assets/debt assessing method is used to gain relative netassets values (relative superiority) of every provincial unit, which are as supporting data forassessment. We also overlaid the Administrative Divisions Map of China and the Map of IntegratedAgricultural Regionalization of China by Geography Information System (GIS) to gain the area unitsof assessment. Third, according to the relative coherence principle of regionalizaticn, we transformadministration units to natural units through homogenizing all provincial relative net assetsvalues in every agricultural assessing unit. After making order and grade, we complete thesustainable developing capability assessment to integrated agricultural regionalization in China.The assessing outcome shows that the total sustainable agricultural developing capability of Chinais not high. Only about 1 /3 in number or in area has reached the level of agricultural sustainabledevelopment. The relative net assets values exists a reducing trend from East China to West China.It needs a long period and great efforts to realize sustainable agricultural development over allChina. Finally, there is a discussion to the study method. 展开更多

Wetland soil quality degradation caused by large-scale agricultural reclamation on the Sanjiang Plain of Northeast China has been widely reported. A relative soil quality evaluation (RSQE) model and a projection pursuit evaluation (PPE) model based on real-coded accelerating genetic algorithm were introduced to evaluate quality variations in top layers of the main wetland soils on the Sanjiang Plain in 1999 and 2003, respectively. As soil quality degradation boundaries were vague, this study established two fuzzy synthetic evaluation (FSE) models based on the original data and criteria used in the RSQE and PPE models. The outputs of the two FSE models were obtained by choosing two fuzzy composite operators M(∧, ∨) and M(·, ⊕). Statistical analysis showed that the results of the FSE, RSQE, and PPE models were correlated. In particular, outputs of the FSE model using M(·, ⊕) were significantly correlated with those of the RSQE model with r = 0.989 at P < 0.01. Compared with RSQE and PPE models, the FSE model may be more objective in showing soil quality variations and was closer to the natural situation, showing the feasibility and applicability of the FSE model in evaluating soil quality degradation. However, the choice of composite operator was of critical importance. The study of wetland soil quality degradation on the Sanjiang Plain was of scientific and practical significance for protection and management of soils and for sustainable development of agriculture in this area in the future. 展开更多

The importance of food security,especially in combating the problem of acute hunger,has been underscored as a key component of sustainable development.Considering the major challenge of rapidly increasing demands for both food security and safety,the management and control of major pests is urged to secure supplies of major agricultural products.However,owing to global climate change,biological invasion(e.g.,fall armyworm),decreasing agricultural biodiversity,and other factors,a wide range of crop pest outbreaks are becoming more frequent and serious,making China,one of the world’s largest country in terms of agricultural production,one of the primary victims of crop yield loss and the largest pesticide consumer in the world.Nevertheless,the use of science and technology in monitoring and early warning of major crop pests provides better pest management and acts as a fundamental part of an integrated plant protection strategy to achieve the goal of sustainable development of agriculture.This review summarizes the most fundamental information on pest monitoring and early warning in China by documenting the developmental history of research and application,Chinese laws and regulations related to plant protection,and the National Monitoring and Early Warning System,with the purpose of presenting the Chinese model as an example of how to promote regional management of crop pests,especially of cross border pests such as fall armyworm and locust,by international cooperation across pest-related countries. 展开更多
