基于城市綠色生產(chǎn)性面積的生態(tài)補(bǔ)償機(jī)制研究
Research on Ecological Compensation Mechanism Based on Urban Ecological Productive Area

摘要：我國城市擴(kuò)張、糧食保障和能源轉(zhuǎn)型形勢嚴(yán)峻，如何挖掘城市建成環(huán)境的綠色生產(chǎn)潛力，探索一條通過糧食和太陽能的生產(chǎn)用于節(jié)約土地空間并緩解生態(tài)壓力的新途徑。本文不同于以往生態(tài)補(bǔ)償研究大多以重點(diǎn)生態(tài)功能區(qū)為對象或以財(cái)稅補(bǔ)償機(jī)制為手段，而是建立城市空間內(nèi)部的生態(tài)補(bǔ)償機(jī)制，是建設(shè)生態(tài)文明的創(chuàng)新方法。本文提出城市“綠色生產(chǎn)性面積”作為一種從城市生態(tài)學(xué)角度來衡量城市生態(tài)承載力提升潛力的方法，它基于將城市綠色資源收入換算成它們所能節(jié)約的相同條件下的生態(tài)足跡。首先，評估城市建成環(huán)境的全要素空間清查及其綠色生產(chǎn)潛力分析。其次，需要建立不同綠色生產(chǎn)的生態(tài)節(jié)地效益統(tǒng)一核算標(biāo)準(zhǔn)，以逆向的生態(tài)足跡方法量化為土地面積指標(biāo)。最后，在綜合考慮城市綠色生產(chǎn)成本、技術(shù)實(shí)施可行性以及生態(tài)服務(wù)價(jià)值的基礎(chǔ)上，采取適宜的都市農(nóng)業(yè)、城市太陽能、農(nóng)業(yè)與太陽能復(fù)合生產(chǎn)等方式，以期對城市生態(tài)系統(tǒng)的生態(tài)承載力給予直接補(bǔ)償，為發(fā)展綠色生產(chǎn)產(chǎn)業(yè)、補(bǔ)償方式多元化、評估生態(tài)節(jié)地效益提供理論和技術(shù)支撐，對于城市可持續(xù)發(fā)展和提高生態(tài)承載力具有重要意義。

Abstract：The situation of urban expansion, food security and energy transformation in China is grim, so how to tap the green production potential of urban built environment and explore a new way to save land space and alleviate ecological pressure through the production of grain and solar energy. Different from the previous ecological compensation studies, which mostly take the key ecological functional areas as the object or the fiscal and tax compensation mechanism as the means, this paper establishes the ecological compensation mechanism within the urban space, which is an innovative method for the construction of ecological civilization. This paper puts forward the urban "green productive area" as a method to measure the promotion potential of urban ecological carrying capacity from the perspective of urban ecology, which is based on converting the income of urban green resources into the ecological footprint under the same conditions that they can save. First of all, evaluate the all-factor spatial inventory of urban built environment and its green production potential analysis. Secondly, it is necessary to establish unified accounting standards for ecological land-saving benefits of different green production, and quantify the land area index with the reverse ecological footprint method. Finally, on the basis of comprehensive consideration of the cost of urban green production, the feasibility of technical implementation and the value of ecological services, appropriate ways of urban agriculture, urban solar energy, agriculture and solar energy compound production are adopted. it is expected to directly compensate the ecological carrying capacity of urban ecosystem and provide theoretical and technical support for the development of green production industry, diversification of compensation methods and evaluation of ecological land-saving benefits. It is of great significance for urban sustainable development and improving ecological carrying capacity.
