摘要
研究目的:归纳阐释土地退化平衡(LDN)对国土空间生态保护修复的理论意蕴,回答LDN导向下国土空间生态保护修复的路径选择。研究方法:逻辑推理法、归纳演绎法。研究结果:(1)LDN具有鲜明的时空特征和明确的响应层次,并遵循“同类平衡(Like for Like)”与“一票否决(One out-All out)”原则。(2)新形势下土地资源的空间载体、生态本底、安全保障、服务双碳目标等功能得到拓展,客观上要求生态保护修复协调好尺度与格局、要素与系统、食物与生态、减排与增汇之间的关系。(3)LDN对生态保护修复的理论意蕴包括多尺度嵌套的动态平衡、多目标权衡的系统治理、多手段协同的实现路径。(4)基于LDN的国土空间生态保护修复策略包括:构建“功能—尺度”与“要素—系统”相耦合的LDN目标函数,引导生态保护修复目标量化;制定螺旋递进式“分区管控—分级治理—分类施策”的管理策略,促进自然与行政区划在空间上的有效衔接;建立“干预管制—激励竞争—强制倒逼—差别治理”协同的保障机制,协调“自然—社会—政府—市场”等多部门关系。研究结论:LDN在国土空间生态保护修复实践中具有积极的理论意义与现实价值,能够将原本抽象的概念具化、空洞的目标量化、感性的修复理性化。
The purpose of this paper is to explain the theoretical implications of land degradation neutrality(LDN)on territorial ecological protection and restoration(TEPR),to propose the solutions of TEPR with LDN orientation.The methods of logical reasoning as well as induction and deduction are employed.The results show that:1)LDN has a clear spatio-temporal scale and response hierarchy,which also needs to follow the principles of“Like for Like”and“One out-All out”.2)Under the new situation,the functions of land resources for space carrier,ecological attribute,security guarantee,and serving carbon peak&neutrality goals have expanded.Thus,these functional expansions further require TEPR to coordinate the relationships between scales and patterns,elements and systems,food and ecology,carbon emission reduction and sink enhancement.3)The theoretical implications of LDN to TEPR comprise 3 aspects:the dynamic balance with multi-scale nesting,the systematic governance with multi-objective trade-offs,and the pathway with multi-instrument synergy.4)The TEPR strategies with LDN orientation are proposed.Firstly,the LDN’s target function composed of“function-scale”and“element-system”is constructed,so as to enable the quantification of TEPR’s targets.Moreover,a spiral and progressive way of“zoning control-classified treatment-differentiated strategy”is proposed,to facilitate the spatial linkage between nature and administration.In addition,a synergistic safeguard mechanism of“interventional control-incentive competition-forced pushback-differential governance”is summarized,to harmonize the relationship between multiple participating sectors of“nature-society-government-market”.In conclusion,LDN has both positive theoretical significance and practical value in the application of TEPR,which could turn the originally abstract concepts into concrete ones,the empty goals into quantitative ones,and the emotional ecological restoration into rational one.
