The dynamic assessment data on the construction effectiveness of high-standard farmland in Xiangshan County can provide scientific and dynamic quality monitoring tools for agricultural management departments. This model, which comprehensively evaluates multi-dimensional indicators including farmland infrastructure, cultivated land quality, ecological protection, and management and protection mechanisms, can reflect the construction quality and long-term benefits of high-standard farmland projects in real time. Its application can help government departments accurately identify areas with substandard construction, optimize subsequent project planning and fund allocation, and avoid resource waste; meanwhile, by dynamically monitoring the operating status of farmland facilities and changes in cultivated land fertility, it can promote the formation of a full-cycle management closed loop from construction to protection and management, and strengthen the sustainable utilization capacity of farmland. This model can also promote the alignment of farmland construction standards with modern agricultural demands, provide data support for national strategies such as improving grain production capacity and protecting black soil, and ultimately achieve the goal of farmland being "constructed to high standards, effectively managed, and delivering sustained benefits".

Unique farmland codes are obtained through special processing based on farmland location information; soil organic matter content (g/kg) Ta is obtained from annual sampling data of cultivated land quality monitoring stations; irrigation guarantee rate (%) Na is obtained from real-time monitoring data of the farmland water conservancy facility management system; field road accessibility (km/mu) J3 is obtained from the acceptance reports of high-standard farmland construction projects; the increase range of cultivated land fertility grade Ma is obtained by comparing the Third National Land Census with the current fertility evaluation; per-mu water saving rate (%) J1 is obtained by comparing water consumption before and after water-saving irrigation projects; mechanized operation coverage rate (%) S is obtained from operation record data of the agricultural machinery dispatching platform; cultivated land connectivity (average plot area/mu) J2 is obtained through remote sensing image recognition and the plot ownership database; disaster prevention and reduction capacity index Ht is obtained from the comprehensive score of historical disaster loss rate and protection facility completeness.

All collected and aggregated data are processed through multi-factor normalization, and finally calculated using the linear weighting method: $Y=((T_a imes0.2)+(N_a imes0.15)+(J_3 imes100 imes0.1)) imes(1+M_a imes0.3)+((J_1 imes0.1+S imes0.15) imes LN(J_2))+H_t imes2$, to obtain the comprehensive effectiveness score of high-standard farmland construction in Xiangshan County. Corresponding management measures are formulated for different score ranges as follows:
1. ≥90 points (Excellent Grade): Promote experience and implement long-term maintenance; include in the provincial high-standard farmland demonstration project database; summarize and promote advanced technologies and management models; prioritize arrangements for management and protection subsidy funds; promote the "integrated construction, management and use" protection and management mechanism;
2. 80-89 points (Good Grade): Carry out precise improvement and consolidate effectiveness; formulate "one zone, one policy" improvement plans for weak links such as irrigation efficiency and soil organic matter; prioritize supporting green production technologies such as water-saving irrigation and organic fertilizer replacement;
3. 70-79 points (Medium Grade): Focus on rectification and conduct special supervision; suspend approval of similar projects; entrust third-party institutions to conduct comprehensive engineering quality inspections; interview project principals; force participation in standardized construction training and re-acceptance; verify core indicators such as irrigation guarantee rate and drainage ditch integrity; start rework procedures;
4. 60-69 points (Fair Grade): Suspend construction for rectification and hold accountable; suspend construction of similar projects county-wide; freeze subsequent fund allocation; have audit departments intervene to investigate the compliance of fund use; hold survey and design institutions accountable;
5. <60 points (Unqualified Grade): Demolish and rebuild and adjust mechanisms; invalidate the project and recover allocated funds; include in the joint credit punishment list; start the cultivated land restoration procedure; demolish substandard facilities and carry out reclamation; adjust the county-level construction management model; pilot the introduction of social capital agency construction mechanism.
