    "abstract": "Let $k\\ge 2$ be a positive integer and let $G$ be a simple graph of order $n$ with minimum degree $\\delta$. A graph $G$ is said to have property $P(k, d)$ if it contains $k$ edge-disjoint spanning trees and an additional forest $F$ with edge number $|E(F)| \u003e \\frac{d-1}{d}(n-1)$, such that if $F$ is not a spanning tree, then $F$ has a component with at least $d$ edges. Let $D(G)$ be the distance matrix of $G$. We denote $\\rho_D(G)$ as the largest eigenvalue of $D(G)$, which is called the distance spectral radius of $G$. In this paper, we investigate the relationship between the distance spectral radius and the property $P(k, \\delta)$. We prove that for a connected graph $G$ of order $n \\ge 2k+8$ with minimum degree $\\delta \\ge k+2$, if $\\rho_D(G) \\le \\rho_D(K_{k-1} \\vee (K_{n-k} \\cup K_1))$, then $G$ possesses property $P(k, \\delta)$. Furthermore, for a connected balanced bipartite graph $G$ of order $n \\ge 4k+8$ with minimum degree $\\delta \\ge k+2$, we show that if $\\rho_D(G) \\le \\rho_D(K_{\\frac{n}{2}, \\frac{n}{2}} \\setminus E(K_{1, \\frac{n}{2}-k+1}))$, then $G$ also possesses property $P(k, \\delta)$. Our results generalize the work of Fan et al. [Discrete Appl. Math. 376 (2025), 31--40] from the existence of $k$ edge-disjoint spanning trees to the more refined structural property $P(k, \\delta)$.",
