Abstract: Abstract: At present, China is in the period of economic and social transformation and the initial stage of ecological civilization construction. The career of China's land consolidation is in unprecedented strategic opportunity period. Now the development of land consolidation is facing a totally new situation, new opportunities, but also many serious challenges. Ecological transformation of land consolidation is the inevitable requirement of the development of the national strategy, but also the trend of the development of land consolidation. Proportion of ecological research literature on land consolidation in research literature on land consolidation is getting higher and higher. Ecological land consolidation research has become an important part of land consolidation research. Based on the study of ecological transformation background of Chinese land consolidation, this paper analyzed the existing ecological problems of land consolidation, discussed the connotation of ecological land consolidation, and proposed "Four development suggestions" for ecological transformation of land consolidation to safeguard the food security and realize the environmental protection function of land consolidation. There are some ecological problems in the current land consolidation work. First, theory method and technology system of ecological land consolidation are not perfect. Compared with developed countries, China's ecological land consolidation technology system seriously lags behind the practical application, and it has not yet formed a systematic scientific theoretical method and technical system for ecological land consolidation. Second, land consolidation is lack of attention to rural culture. Some places in the land consolidation simply pursue quantity of cultivated land and modern architectural styles, and ignore the protection of rural culture. Third, ecological land consolidation is lack of new ecological material and new technology, which is difficult to meet the needs of the development of ecological land consolidation. This paper stated that in the era of ecological civilization construction, land consolidation is no longer a simple planning and construction of land use. Ecological land consolidation should combine land consolidation with traditional culture and regional development, improve its implementation path, public participation and development model, and reduce ecological pressure and its negative impact. The ecological environment effects should be considered in the process of land consolidation. And protecting the ecological environment should be the main target of land consolidation. The goals of intensive production, enhancing quality of life, and improving ecological environment should be realized through the "quantity control, quality management, ecological protection and management". According to the ecological environment problems in land consolidation, this paper proposed "Four development suggestions", which are 1) promoting the awareness of the ecological effect of land consolidation; 2) improving the study of theory and technology system of ecological land consolidation; 3) accelerating the development of new ecological material and new technology of land consolidation work; 4) strengthening public participation, and paying attention to the protection of rural landscape and the application of local techniques. With these 4 suggestions, land consolidation can be regarded as the powerful supporter and important platform to maintain food security and protect the environment in an all-round way. Of course, the legal system is also needed to promote the transformation of ecological land consolidation. Improving land consolidation planning system, and strengthening education are also the important guarantee of ecological transformation of land consolidation.
